Git Integration

Currently we have to compare the mismatch manually then copy the file over if it's good. Wondering if there's some way to just overwrite the current snapshot but fail the unit test if the file is considered changed by git.

That way I can just use the in built diff tools really easily and just use git commit as a way to approve.

Does means tests won't initially work until they're commited which might not be great, but certainly has potential to reduce required tooling/overhead.

potentially just a way to replace ISnapshotFileHandler might allow something like this?
