DM's striking off into its own JSON world. This gets strawman implementations
in place for writing and reading a JSON file mapping test name to hashes.
For what it's worth, I basically want to change _all_ these pieces,
- MD5 is slow and we can replace it with something faster,
- JSON schema needs room to grow more data,
- it'd be nice to hash once instead of twice when reading and writing,
- this code wants lots of refactoring,
but this gives us a starting platform to work on these bits at our leisure.
E.x. file for now:
