    Connect my checkstyle9.pl script to a action.
    
    Connect the checkstyle9.pl script to a github action. This will provide
    feedback to people submitting changes when the style is grossly wrong. And
    can provide other automated feedback for the commit message in the future.
    It already catches the github noreply author.
    
    It pulls the full repo to do this. Optimizations welcome. After messing
    with that for a few hours, I decided to punt and commit the slow, working
    version and let someone else optimize from here.
