Fixes #13

Also found what I think is a bug in TRIO100, and added TRIO106 to README.md

Nice ✅

Quick style note, if you're comfortable with pytest-style test functions I'm just as happy to use those as unittest classes.

I haven't used either extensively enough to have too much of an opinion - but I needed access to a msg parameter to give more info and the first place I looked that had it was unittest.

Even better would be to have multiple different tests generated for each file, instead of it quitting on the first file/test pair that fails, but didn't bother spending time on figuring out how to do that.

assert condition, "message" is the pytest idiom fyi 🙂

Agree that it's not worth extending further though!

Thank you, good to know!
