This updates the caching of address histories to match the pattern used in scribe, which is much more performant. In addition to caching the final address histories, the tx_hash and heights are also cached in a smaller (but more items) cache that allows for a high hit rate on blocks containing transactions that touch many addresses (where each touched address has a fairly large history).

Additionally, the history cache is now updated in place using a minimal set of batched lookups upon a new block instead of being cleared.
