Upgrade to bdk 4.0
To achieve this we also:

- upgrade rust-bitcoin to 0.26
- upgrade bitcoin-harness to latest version (which also depends bitcoin 0.26)
- upgrade to latest edcsa-fun
- replace cross_curve_dleq proof with sigma_fun (to avoid an upgrade dance over there)

200: Wait for refund if insufficient Monero is locked up r=da-kami a=da-kami

In a scenario where Alice does not lock up sufficient funds Bob should properly transition to refunds. At the moment the CLI just panics. 
I noticed this when Alice accidentally had a different amount set than Bob. In the future this should not happen, because Alice provides the amount for Bob. However, in case Alice is malicious Bob should still transition correctly.

190: Do not pass Monero amount to the CLI r=D4nte a=D4nte

The CLI user only pass the Bitcoin amount they want to sell.

The CLI then do a quote request to nectar which provides the Monero amount the taker can get.

Also align terminology with the sequence diagram.

Make config argument global
The `config` argument apply to all commands. It is now optional and
needs to be passed before a command.
E.g. `cli --config ./config.toml history`

Remove acknowledgements processing
We are aware of issues of timeouts when waiting for acknowledgements.
Also, to properly supports acks in a multiple swap context, we need to
revert to doing event processing on the behaviour so that we can link
leverage the `RequestResponse` libp2p behaviour and link the messages
requests ids to swap ids when receiving an ack or response.

Acks are usefully for specific scenarios where we queue a message on the
behaviour to be sent, save as sent in the DB but crash before the
message is actually sent. With acks we are able to resume the swap,
without ack, the swap will abort (refund).

Remove unnecessary channels
`alice::swap::run_until` will be called once the execution setup is
done. The steps before are directly handled by the event loop,
hence no channels are needed for said steps: connection established,
swap request/response & execution setup.

Prepare separation of event loop initialisation to swap initialisation
As for Alice, the event loop will be started with the program and will
be the one starting swaps (`run_until`) based on libp2p events (swap
request).

Allow EventLoop to hold a database ready to pass to alice::Buider
The `EventLoop` will use the `Builder` interface to instantiate a
`Swap` upon receiving a `SwapRequest` and successfully doing an
execution setup.
Before this change, the `EventLoop` would have to hold the path to the
db and re-open the db everytime it wants to construct a swap.

With this change, we can open the DB once and then hold a
`Arc<Database>` in the `EventLoop` and pass it to new `Swap`s structs.

53fcd9224c Give finding the refund tx priority over waiting for the punish transaction to be finalized.
This was introduced due to a CI run, where Bob included tx_refund, but Alice had waited until T2 had expired,
and then went for punishing Bob instead of refunding.
Weirdly, Alice's punich transaction did not fail in that scenario.

2d5d70d856 Timeout for Alice waiting for ack for sending transfer proof
If dialing Bob fails Alice waits for the acknowledgement of the transfer proof indefinitely.
The timout prevents her execution from hanging.
Added a ToDo to re-visit the ack receivers. They don't add value at the moment and should be removed.
