0.2rc1

This is a pre-release, for testing purpose!

0.2: now with multisig support!

The second release of Liana brings various fixes as well as the possibility to use a multisig in
either, or both, of the spending paths.

Features

• Multisig: we now support descriptors with multiple keys both in the primary (non-timelocked)
  spending path and the recovery (timelocked) path.

GUI-specific

• You can now import and update Spend transaction drafts as PSBTs to collaboratively create and sign
  transactions.
• When creating a new descriptor you can now set an alias for each key. Those will be displayed when
  inspecting a transaction's signatories.
• Amounts are now displayed with the sats in bold for better redability.

Fixes

• We now remove the fixed interpreter and rpath set by GUIX reproducible builds in the liana-cli
  ELF binary.
• We now check the bitcoind version before trying to import a Miniscript descriptor.
• We now discard unconfirmed incoming payments that were dropped from our mempool.

GUI-specific

• Various wording fixes on the UI.
• Amounts are now updated when moving between steps in the Spend creation flow.
• Coins are now sorted by age when displayed as a list.
• Some flakiness in the connection to a signing device were fixed.
• The descriptor registration on a signing device step in the installer was made clearer.
