Consolidates sane flake8 settings to pyproject with the Flake8-pyproject plugin.
Does not change logic of test workflow but allows base settings to live in pyproject for anyone using flake8 as an external linter (e.g. vscode)
Also fixes some flake8 errors that were not being picked up by current testing, mostly unused imports.
Standardizes shebang and coding declarations.
Coding matches what's used by install tools such as pip(x).
Removes a few init files that were not needed.
