Added type annotations to all functions (#845)

* Added type annotations for 1/5 of the files.

There's bound to be some issues with type miss-match, will sort that out later.

* Added type hints for 4/5 of the code

* Added type hints for 4.7/5 of the code

* Added type hints for 5/5 of the code base

* Split the linters into individual files

This should help with more clearly show which runner is breaking since they don't share a single common name any longer. Also moved mypy settings into pyproject.toml

* Fixed some of the last flake8 issues

* Missing parameter

* Fixed invalid lookahead types

* __future__ had to be at the top

* Fixed last flake8 issues
