fix(writer): Emit checksum event when verifying bmaps (#1859)

Browse Source 
Due to the Blockmap.FilterStream not emitting a "checksum"
event (as it individually verifies specified ranges), the
flashing process would get stuck on finish.

This emits a "checksum" event on "finish" when blockmapping,
averting this issue.
