Improve type checking, move into dir, refactor into functions

The module has been moved into a module directory, due to py.typed not
taking effect otherwise. The module has been refactored so that the work
is divided into more concise and atomic functions. This may improve
patching in the long term. Type annotations were revised and improved,
although there is still some room for improvement.
