Each test spawns swarm for Alice and Bob that only contains the spot_price behaviours and uses a memory transport.
Tests cover happy path (i.e. expected price is returned) and error scenarios.
Implementation of `TestRate` on `LatestRate` allows testing rate fetch error and quote calculation error behaviour.
Thanks to @thomaseizinger for ramping up the test framework for comit-rs in the past!
Instead of handling all errors on the inside spot_price errors are bubbled up (as `SwapRequestDeclined`).
This allows us to test both Alice's and Bob's behaviour for all scenarios.
What goes over the wire should not be coupled to the errors being printed.
For the CLI and ASB we introduce a separate error enum that is used for logging.
When sending over the wire the errors are mapped to and from the `network::spot_price::Error`.
As part of Bob-specific spot_price code was moved from the network into bob.
Clearly separation of the network API from bob/alice.
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`).
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.
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.
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.

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.

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