Derived from this comment: https://github.com/paritytech/substrate/pull/12753/files#r1031660875

In-flight finality notifications might get lost on client crashes/restarts. In order to account for this we need to:

  1. remember the last canonicalized block and canonicalize all the blocks between it and the blocks contained in the current finality notification if any
  2. persist some state for the MMR gadget
