Fix acknowledge comments (#126)

* debugging: give test name based on input folder

* change LintError to typing.NamedTuple for type info

* add some more test ids

* update format

* handle new way of dealing with multiple violations on a line

* handle that comments can trigger W505.

* format

* update tests

* handle lint errors

* these aren't valid code files that can pass black

* update tests

* this doesn't get used like we thought it did

* make spacing consistent

* bump patch version

* cleanup leading spaces

* add test that old comment stile is removed on --aggressive
