Epoching module used to remember the AppHash of every block, in order to prove a consumer header is committed to a Babylon header. This is no longer needed, as now we generate proof that a consumer header is committed to the sealer header of an epoch directly. Yet, its overhead is not negligible in terms of computation (upon each epoch we need to generate a Merkle root) and storage (we need to remember every AppHash). Thus this PR proposes to remove it.
