In this commit, we fix an existing bug with the taproot channel type that can cause force closes if a peer disconnects while attempting to send the commitment signature. Before this commit, since the `PartialSig` we send is never committed to disk, the version read wouldn't contain the musig2 partial sig. We never write these signatures to disk, as each time we make a new session, we need to generate fresh nonces to avoid nonce-reuse. Due to the above interaction, if we went to re-send a signature after a disconnection, the `CommitSig` message we sent wouldn't actually contain a `PartialSigWithNonce`, causing a protocol error. |

lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
