Incremental snapshots only calculate their accounts hash based on the
account changes WITHIN the incremental slot range. So, we need to keep track
of the full snapshot expected accounts hash results. We also need to keep
track of the hash and capitalization specific to the incremental snapshot
slot range. The capitalization we calculate for the incremental slot will
NOT be consistent with the bank’s capitalization. It is not feasible to
calculate a capitalization delta that is correct given just incremental
slots account data and the full snapshot’s capitalization.
