module indexer introduces a extensible architecture for indexing the chain. It provides a base class which handles syncing with the chain, handling re-orgs, interruptions, dynamic toggling, etc. TXIndexer and AddrIndexer are provided for indexing transactions and addresses, using the same flags as before i.e --index-tx and --index-address. Indexes are stored in a different database and can be maintained independently of the chain.
