upgrade(swap): Concurrent syncing, bdk upgrade, refactors (#180)

* upgrade sqlx to 0.8, add bdk_wallet and bdk_electrum

The new dependencies are part of the bdk upgrade and
include the improved wallet code.
They, too, depend on sqlite3.
However, they use a newer version than we currently use via sqlx.
This necessitated the sqlx upgrade.
This entailed trivial changes (use Pool directly instead of pool.acquire()).
We might have to fix the CI as well, I kept getting compile
errors from the macro until I ran swap/sqlx_dev_setup.sh.

* move old wallet code to extra module

* fix fee estimation for old client

 ## [Unreleased]
 
+- CLI + ASB + GUI: We upgraded dependencies related to the Bitcoin wallet. When you boot up the new version for the first time, a migration process will be run to convert the old wallet format to the new one. This might take a few minutes. We also fixed a bug where we would generate too many unused addresses in the Bitcoin wallet which would cause the wallet to take longer to start up as time goes on.
