Tests

Identifying what areas would benefit from test coverage and writing them.

I propose a replay from every protocol along with the extract from that replay as verified against the heroprotocol python library.

Our tests would be then be to test extraction of that replay, and verify it against the extracted data already in the test/ directory. It bumps up the size of the repo considerably, but none of this goes in the npm package, so does it really matter?

The other option is to checksum the extracted files and only include the checksum in the tests.

Let me know, and I can get started.
