Improvements to extractors service #76

Description

@Tburm

The process of making historical RPC calls and storing them is not ideal, since it creates heavy RPC load for backfills or new deployments. Luckily cryo reviews the existing directory and fetches minimal data, so zipped archives can potentially avoid this issue using a backup.

Additionally, there could be more friendly alternatives to collect this data. Cryo includes a way to query specific traces, and storage diffs on some chains.

Tasks:

  • Test fetching traces and state diffs using cryo
  • Evaluate possibility of using traces to replacegetVaultCollateral and getVaultDebt calls make using cryo and eth_call
