This is looking pretty good. I tried to upgrade the type hints, you'll probably want to double-check that I put them in correctly before accepting the suggestions. (see note below on the one I'm not sure about)

Other than improving the type hints, I think this is ready to merge.

@terriko Happy with the suggestions. version_scanner.py needs type hints to be added to the rest of the functions but that can be picked up as part of the general tidy up of adding type hints across all of the modules.
