Figure out why codehash=>code is not being stored correctly

[i-norden]

Currently writing the tx_data for deployment txs as the codebytes, this is not producing the correct code hashes. There must be some processing step on the tx_data before it is stored as codebytes.

• Create http endpoint for statediffing geth to fetch all codehash => code pairs

• Modify the statediffing service to emit codehash => code pairs for any deployment txs at the payload's block height

• Adjust ipld-eth-indexer sync/backfill/resync to consume and index emitted pairs

• Script/ipld-eth-indexer command to fetch missing historical from the http endpoints

• Script to remove malformed entries (optional)

Deployed data can be modified by the EVM before it is stored by geth as a codehash=>code mapping. The EVM requires a state database, which complicates modifying the code on the ipld-eth-indexer end.

Alternative approach:

1. Create http endpoint for statediffing geth to fetch all codehash => code pairs
2. Modify the statediffing service to emit codehash => code pairs for any deployment txs at the payload's block height
3. Adjust ipld-eth-indexer sync/backfill/resync to consume and index emitted pairs
4. Script/ipld-eth-indexer command to fetch missing historical from the http endpoints
5. Script to remove malformed entries (optional)
