b8fec4b571 Add WriteStateSnapshot (#15)

Adds a method to perform full-state snapshots by diffing against an empty state trie.
This replicates the functionality of `ipld-eth-state-snapshot`, so that code can use this as a library; see: cerc-io/ipld-eth-state-snapshot#1

Note that due to how incremental diffs are processed (updates are processed after the trie has been traversed) the iterator state doesn't fully capture the progress of the diff, so it's not currently feasible to state diffs this way. Full snapshots don't have to worry about updated accounts, so we can support them.

981bfb5895 Use symmetric difference iterator (#11)
All checks were successful
Test / Run unit tests (push) Successful in 17m53s
Test / Run integration tests (push) Successful in 37m51s
Implements https://github.com/cerc-io/go-ethereum/issues/319

With this we can perform a single pass to process updates.

Also
* refactor code structure around single-pass iteration
* refactor builder metrics to match new set of functions
* fix unit tests by running sequentially
* update ipld-eth-db in compose
* factor out fixture data into external module
* some CI updates
