Return proper error to CLI for all expected scenarios
When a CLI requests a spot price have some errors that are expected, where we can provide a proper error message for the CLI:
- Balance of ASB too low
- Buy amount sent by CLI exceeds maximum buy amount accepted by ASB
- ASB is running in maintenance mode and does not accept incoming swap requests

All of these errors returns a proper error to the CLI and prints a warning in the ASB logs.
Any other unexpected error will result in closing the channel with the CLI and printing an error in the ASB logs.

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.

Merge #466
466: Add support to dynamically chose bitcoin transaction fees.  r=bonomat a=bonomat

Resolves #443 (Bitcoin only). 

@da-kami  /@thomaseizinger: do you know how fees work in Monero? 
If not, I'll read up on it and to come up with a proper strategy. 

Monero Fees will be covered in #470

Note: 
The there is a hardcoded relative and absolute upper bound. I personally feel safer if this is hardcoded for now as it is too easy to get wrong. 
At the time of writing, this equals roughly USD $56. 
Eventually we will want to make this also configurable.

Add upper bound for bitcoin fees of 100,000 satoshi.
Fees are hard to compute and it is too easy to get wrong and lose a lot of money. Hence, a hardcoded maximum of 100,000 satoshi for a single transaction is in place.

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.

Dynamically chose fee for TxRefund and TxPunish.
Alice chooses the fee for TxPunish because she is the one that cares.
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.

434: Introduce monero-wallet crate r=thomaseizinger a=thomaseizinger

This PR:

1. ~Introduce a crate for the epee binary serialization as a serde format~: Released here: https://github.com/comit-network/monero-epee-bin-serde
2. Extends the MoneroRPC client with two binary calls
3. Introduces a `monero-wallet` crate that for now just provides functionality for choosing random key offsets. Together with the the ability to produce bulletproofs and ring signatures, this should be enough for signing Monero transactions locally.

(1) and (2) are a prerequisite for (3).

Merge #460
460: Different default directories for CLI and ASB r=da-kami a=da-kami

Fixes #437 

Using the same default directory as data-/config-dir has caused unwanted side effects when running both applications on the same machine.
Use these directory names:
- ASB: `xmr-btc-swap-asb`
- CLI: `xmr-btc-swap-cli`

Since the functionality is now application specific the respective functions were moved into the appropriate module of the application.

Merge #459
459: Use dprint for formatting Cargo.toml files r=thomaseizinger a=thomaseizinger

Invoking cargo tomlfmt on all files is a PITA and as we can see from
the CI scripts, it is often forgotten to as new crates are added to
the workspace.

Using dprint for toml files fixes this.

Unfortunately, we can't use dprint for Rust code yet because there
hasn't been a release of rustfmt in quite a while but we are already
using features from a newer rustfmt via rustup.

Introduce monero-wallet crate
This is fairly bare-bones for now and only contains one piece of
functionality: choosing random key offsets.

More functionality for actually signing Monero transactions will
be added later.

Merge #451
451: Peer id check for transfer proof and encsig messages r=da-kami a=da-kami

Fixes #416 

The second commit will be relevant for changes planned in #411 

@thomaseizinger with #411 we will need access to Bob's database in the eventloop, this might influence design decisions for #401

Peer check for incoming transfer proofs
Bob validates that incoming transfer proof messages are coming from the peer-id of Alice.
Currently Bob will ignore any transfer proof message that is not coming from the counterparty peer-id associated to the current swap in execution.
Once we add support for trying to save received transfer proofs for swaps that are currently not in execution we can also adapy allowing this for different counterparty peer-ids. This requires access to the database in Bob's event loop.

Peer check for incoming encrypted signatures
Alice validates that incoming encsig messages are coming from the peer-id that is associated with the swap.
Encsig message from a peer-id different to the one associated with the swap are ignored.
