Rob Mulholand 867f92c431 (VDB-298) Consume Pit contract storage diffs
- Continuously parse storage diffs CSV data to read Pit contract state
- Convert ilks in database to raw bytes32 value for use in generating
  storage keys dynamically
- Persist storage diffs with block number and hash for validation
