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.
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.
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).

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.

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.

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

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.
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.

438: Add support for swapping through Tor. r=bonomat a=bonomat
Resolves: #447
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.
Note: It is expected that the new test will fail on CI because we do not have Tor running. That's why it wasn't added yet. I'll play around in my own fork to not use precious CI resources :)
The rest is ready for review.
// edit:
Swapping through Tor on one machine seems to be working:
