In order to be able to re-connect on certain errors, we model
connection errors separately from parsing errors. We also change
the API of the whole module to no longer forward all errors to
the subscribers but instead, only update the subscribers with
either a latest rate or a permanent failure in case we exhausted
all our options to re-connect the websocket.
To model all of this properly, we introduce to sub-modules so that
each submodule can have their own `Error` type.
Resolves#297.
First, we tell the user that we are now waiting for Alice to lock
the monero. Additionally, we tell them once we received the
transfer proof which will lead directly into the
"waiting for confirmations" function.
291: Improve CLI help comments and "type" hints r=rishflab a=rishflab
The type hints are generated from the field names. This has the
unfortunate consequence of the config field becoming file_path which
does not really make sense people working on the codebase.

290: Monero daemon host configurable r=rishflab a=da-kami
Note: `monero-daemon-host` in accordance with the wallet RPC params, from wallet RPC help:
```
Usage:
monero-wallet-rpc [--wallet-file=<file>|--generate-from-json=<file>|--wallet-dir=<directory>] [--rpc-bind-port=<port>]
General options:
--help Produce help message
--version Output version information
Wallet options:
--daemon-address arg Use daemon instance at <host>:<port>
--daemon-host arg Use daemon instance at host <arg>
instead of localhost
```

The bitcoin::Wallet::sync_wallet function doesn't do anything else
other than delegating. As such, we have just as much information
about what went wrong inside this function as we have outside.
By moving the .context call into the function, we can avoid repeating
us on every call-site.
288: Switch to public stagenet node that works r=rishflab a=rishflab
The xmr.to node has been unreliable lately. The exan.tech node seems to
working.
@da-kami is following up with making this configurable. Lets get this in so we can get a release on Friday.

284: Rename `latest` release to `preview` r=thomaseizinger a=thomaseizinger
The latest release should refer to the latest non-pre release.
What we are doing here is actually publishing a preview release.
Fixes#281.
286: Update Cargo.lock for new version r=thomaseizinger a=thomaseizinger
I forgot about this in the last commit ...

Instead of leaking the tokio::sync:⌚:Receiver type in our
return value, we create a newtype that implements the desired
interface. This allows us to get rid of the `RateService` structs
and instead implement `LatestRate` directly on top of this struct.
Given that `LatestRate` is only used within the event_loop module,
we move the definition of this type into there.
271: Bob can verify that the XMR lock tx was published r=da-kami a=da-kami
The Monero `txhash` log was removed. I feel the user should have the possibility to verify that the transaction was actually published so I added the tx-hash to the confirmation output.
We could potentially print the tx-hash when receiving the transfer proof already, but that might not add much value compared to printing it with the confirmations.
Additionally we should allow the user to at least know when the XMR can be expected in the user's wallet, otherwise the swap ends like this:
```
2021-03-04 13:49:19 INFO Monero lock tx received 5 out of 5 confirmations
```
This is just not very informative - yes, the final transaction is an implementation detail, but I don't think we should hide the transactions from the user. By printing the tx-hash for spending from the lock-tx into the user wallet we ensure the user knows that the XMR can now be expected in the user wallet.
