added subcommand `state_domains` of `bin/integration` to start
processing of existing chaindata with use of state domains and
commitment.
It creates two directory in `datadir`: `state` and `statedb` for files
and mdbx respectively.
This version runs blocks one after another and produces merged files.
Want to add some metrics to export later.
This is a partial implementation of eth_getProof (see issue #1349),
supporting only a request for the latest block and an empty list of
storage keys (i.e. Account proof only). I don't know if there's a better
way of implementing this, but this was what I could come up with.
Posting it here in case it's useful.
Example output:
```

Passing consensus-specs tests for Capella. Processing of withdrawals and
ExecutionChanges. efficient non-validation implemented. Refactored:
ExecutionPayload/ExecutionPayloadHeader.
This branch implements support of btree indexes instead of .kvi files.
Kvi also created, but not used during search/lookup, only for size
comparation.
Btree allows to make seek calls, while recsplit indexes does not support
that query.
During initial tests, btree indexes are ~1-3% smaller than recsplit but
avg lookup time bigger up to 1.5us (which compensates with ability to
fetch next key).
