git action on changed analyses

[MarkGotham]

• for file in changed files:
• if file extension in ['rntxt', 'txt']
• check it parses

Or, a more detailed alternative to consider:

• parse the score and analysis pair for both before and after condition,
• run the umpire, get overall % metric on both,
• set a percentage tolerance. Doesn't have to actually improve every time, but shouldn't break it.
