New Features
- Sweep Batcher: A new sub-system was added that handles all the loopout
sweeps. Successful loopout HTLCs will no longer be swept back to the wallet via
individual transactions but will instead form a single transaction that holds
multiple inputs and pays to a single output. This will significantly reduce
chain fee costs as it's using less block space by directly consolidating all the
htlcs to a single address. Loopouts that pay to non-wallet addresses will still
use individual transactions as their output cannot be mutated.
