v0.27.0-beta

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.
