build(deps): update rust-toolchain to 1.67 and bump uuid to 1.4
some of the dependency updates are requiring a higher version of the
rust toolchain. bump to 1.67 and fix new clippy lints.

also fix dprint to 0.39.1 because 0.40 has breaking changes.

Record the monero-wallet-restore blockcheight before locking BTC
This solves issues where the CLI went offline after sending the BTC transaction, and the monero wallet restore blockheight being recorded after Alice locked the Monero, resulting in the generated XMR redeem wallet not detecting the transaction and reporting `No unlocked balance in the specified account`.

Integrate rendezvous protocol into ASB
The rendezvous protocol allows us to register all of our external
addresses. Hence, the first step is to allow the user to configure
external addresses as part of the config. In the future, there might
be an automated way of determining these.

To register with a rendezvous node, the user needs to configure which
one. CoBloX is running a rendezvous node that acts as the default by
every spec-compliant node will do the job just fine. This behaviour
is optional which is why our custom behaviour is wrapped in a `Toggle`.

We also want our node to re-register after half the time of the
registration has passed. To make this simpler and allow for testing in
isolation, we create a custom behaviour that wraps the libp2p rendezvous
behaviour.

Move files from protocol to appropriate module
Some network and application specific code does not belong in the protocol module and was moved.
Eventloop, recovery and the outside behaviour were moved to the respective application module because they are application specific.

The `swap_setup` was moved into the network module because upon change both sides will have to be changed and should thus stay close together.

swap_setup instead of spot_price and execution_setup
Having `spot_price` and `execution_setup` as separate protocols did not bring any advantages, but was problematic because we had to ensure that `execution_setup` would be triggered after `spot_price`. Because of this dependency it is better to combine the protocols into one.

Combining the protocols also allows a refactoring to get rid of the `libp2p-async-await` dependency.

Alice always listens for the `swap_setup` protocol. When Bob opens a substream on that protocol the spot price is communicated, and then all execution setup messages (swap-id and signature exchange).

Alice's spot price logic into dedicated behaviour
Move Alice's spot price logic into a dedicated network behaviour that handles all the logic.
The new behaviour encapsulates the complete state necessary for spot price request decision making.
The network behaviour cannot handle asynchronous calls, thus the balance is managed inside the spot price and has to updated regularly from the outside to ensure the spot price balance check has up to date data.
At the moment the balance is updated upon an incoming quote requests.

Code that is relevant for both ASB and CLI remains in the `network::spot_price` module (e.g. `network::spot_price::Error`).

Add resume-only mode for the ASB
Resume-only is a maintenance mode where no swaps are accepted but unfinished swaps are resumed.
This is achieve by ignoring incoming spot-price requests (that would lead to execution setup) in the event-loop.

Dynamically calculate fees using electrum's estimate_fee.
Electrum has an estimate-fee feature which takes as input the block you want a tx to be included.
The result is a recommendation of BTC/vbyte.
Using this recommendation and the knowledge about the size of our transactions we compute an appropriate fee.
The size of the transactions were taken from real transactions as published on bitcoin testnet.
Note: in reality these sizes might fluctuate a bit but not for much.

Bob chooses the fee for TxRefund because he is the one that cares.

Note must be taken here because if the fee is too low (e.g. < min tx fee) then she might not be able to publish TxRedeem at all.

Add support for swapping through Tor.
This PR does a few things.
* It adds a TorTransport which either dials through Tor's socks5 proxy or via clearnet.
* It enables ASB to register hidden services for each network it is listening on. We assume that we only care about different ports and re-use the same onion-address for all of them. The ASB requires to have access to Tor's control port.
* It adds support to dial through a local Tor socks5 proxy. We assume that Tor is always available on localhost.  Swap cli only requires Tor to be running so that it can send messages via Tor's socks5 proxy.
* It adds a new e2e test which swaps through Tor. For this we assume that Tor is currently running on localhost. All other tests are running via clear net.

Refactor monero-harness containers
1. Split up image::Monero into Monerod and MoneroWalletRpc
2. Don't use `bash` to run the internal command. Instead we disable
the entrypoint script as per https://github.com/XMRto/monero#raw-commands
3. Remove the start up delay by listening for the correct log message.
To make this more resilient, we make the log level NOT configurable and
instead always log verbosely.

Multiple swaps with the same peer
- Swap-id is exchanged during execution setup. CLI (Bob) sends the swap-id to be used in his first message.
- Transfer poof and encryption signature messages include the swap-id so it can be properly associated with the correct swap.
- ASB: Encryption signatures are associated with swaps by swap-id, not peer-id.
- ASB: Transfer proofs are still associated to peer-ids (because they have to be sent to the respective peer), but the ASB can buffer multiple
- CLI: Incoming transfer proofs are checked for matching swap-id. If a transfer proof with a different swap-id than the current executing swap is received it will be ignored. We can change this to saving into the database.

Includes concurrent swap tests with the same Bob.

- One test that pauses and starts an additional swap after the transfer proof was received. Results in both swaps being redeemed after resuming the first swap.
- One test that pauses and starts an additional swap before the transfer proof is sent (just after BTC locked). Results in the second swap redeeming and the first swap being refunded (because the transfer proof on Bob's side is lost). Once we store transfer proofs that we receive during executing a different swap into the database both swaps should redeem.

Note that the monero harness was adapted to allow creating wallets with multiple outputs, which is needed for Alice.

Wait for lock tx and send transfer proof in separate state
Sending the transfer transaction in a distinct state helps ensuring
that we do not send the Monero lock transaction twice in a restart
scenario.
Waiting for the first transaction confirmation in a separate state

Alice aborts if any timelock expired before locking XMR
Once we resume unfinished swaps upon startup we have to ensure that
it is safe for Alice to act.
If Bob has locked BTC it is only make sense for Alice to lock up the
XMR as long as no timelock has expired. Hence we abort if the BTC is
locked, but any timelock expired already.
