Improve time formatting of log output
Previously, the time was formatted as ISO8601 timestamps which is
barely readable by humans. Activating the `chrono` feature allows
us to format with a different format string. The output now looks
like this:

2021-03-01 11:59:52  DEBUG Database and seed will be stored in /home/thomas/.local/share/xmr-btc-swap
2021-03-01 11:59:52  DEBUG Starting monero-wallet-rpc on port 40673

2021-03-01 11:59:59  DEBUG Dialing alice at 12D3KooWCdMKjesXMJz1SiZ7HgotrxuqhQJbP5sgBm2BwP1cqThi
2021-03-01 11:59:59  DEBUG Requesting quote for 0.00008795 BTC

There is a double space after the time which is already fixed in
tracing-subscriber but not yet released.

bb1537d6f2 Error feedback for the user upon communication errors
If communication with the other party fails the program should stop and the user should see the respective error.
Communication errors are handled in the event-loop. Upon a communication error the event loop is stopped.
Since the event loop is only stopped upon error the Result returned from the event loop is Infallible.

If one of the two futures, event loop and swap,  finishes (success/failure) the other future should be stopped as well.
We use tokio::selec! to stop either future if the other stops.

e66e84085b Rename Bob's Behavior Failure to CommunicationError
Failure does not express what the error represents. It is only used for communication
errors for quote requests, receiving the XMR transfer proof and sending the encryption signature.

Remove --send-btc in favor of swapping the available balance
If the current balance is 0, we wait until the user deposits money
to the given address. After that, we simply swap the full balance.

Not only does this simplify the interface by removing a parameter,
but it also integrates the `deposit` command into the `buy-xmr`
command.

Syncing a wallet that is backed by electrum includes transactions
that are part of the mempool when computing the balance.
As such, waiting for a deposit is a very quick action because it
allows us to build our lock transaction on top of the yet to be
confirmed deposit transactions.

This patch introduces another function to the `bitcoin::Wallet` that
relies on the currently statically encoded fee rate. To make sure
future developers don't forget to adjust both, we extract a function
that "selects" a fee rate and return the constant from there.

Fixes #196.

Remove BuildTxLockPsbt and GetNetwork traits
These traits were only used once within the `TxLock` constructor.
Looking at the rest of the codebase, we don't really seem to follow
any abstractions here where the protocol shouldn't know about the
exact types that is being passed in.

As such, these types are just noise and might as well be removed in
favor of simplicity.

Remove syncing wallet log
BDK already has a log line for the sync that we could enable if we

Additionally, _we_ are not actually syncing the wallet, bdk is so our
log line was lying. It should have said "calling bdk to sync wallet".

231: Error only on close message when fetching the rate r=thomaseizinger a=da-kami

Ping/Pong messages disturb the rate requests quite frequently resulting in failed swap setup because there is no rate available.

As a result messages Ping, Pong and Binary are now ignored and not reported as error.

Download and run monero wallet rpc on swap cli startup
If the monero wallet rpc has not already been downloaded we download the monero cli package and extract the wallet rpc. The unneeded files are cleaned up. The monero wallet rpc is started on a random port which is provided to the swap cli.

We added a fork of tokio-tar via a git subtree because we needed a tokio-tar version that was compatible with tokio 1.0. Remove this subtree in favor of a regular cargo dependency when this PR merges: https://github.com/vorot93/tokio-tar/pull/3.

1404057dbe Remove misleading TODO
This TDOO is misleading, because - to our current knowledge - it is impossible for
Bob to retrieve the exact inclusion block-height of the lock transaction (send by Alice).
The wallet RPC is only capable of retrieving the inclusion block height of a transaction
through `get_payments` and `get_bulk_payments` which requires the `payment_id`.
The `payment_id` can be retrieved through `get_transfer_by_txid` which states
"Show information about a transfer to/from this address." - however the address that the
transfer goes to is not part of Bob's wallet yet! Thus, it is impossible for Bob to use
`get_transfer_by_txid` which in turn means Bob is unable to use `get_payments`.

The only possible way for Bob to know the exact inclusion block/height of the lock transaction
would be if Alice sends it over to Bob. But for that Alice would have to extract it she would have
to wait for confirmation - which she currently does not and might never do. Even if she does await
the first confirmation before sending the transfer proof the solution for retrieving the inclusion
block-height is not fleshed out on her side yet.

9f1deb9fdc Wrap the Monero wallet client in a Mutex
In order to ensure that we can atomically generate_from_keys and then reload a wallet,
we have to wrap the client of the monero wallet RPC inside a mutex.
When introducing the Mutex I noticed that several inner RPC calls were leaking to the
swap crate monero wallet. As this is a violation of boundaries I introduced the traits
`GetAddress`, `WalletBlockHeight` and `Refresh`.

Note that the monero wallet could potentially know its own public view key and
public spend key. If we refactor the wallet to include this information upon wallet
creation we can also generate addresses using `monero::Address::standard`.
