The top-level package contains the implementation of the `vm.StateDB` interface that accesses state directly using the
`state_cids` and `storage_cids` tables in ipld-eth-db. The `trie_by_cid` package contains an alternative implementation
which accesses state in `ipld.blocks` through the typical trie traversal access pattern (using CIDs instead of raw
keccak256 hashes), it is used for benchmarking and for functionality which requires performing a trie traversal
(things which must collect intermediate nodes, e.g. `eth_getProof` and `eth_getSlice`).
