Refactor: remove __init__.py files meant for Python versions before 3.3 (#160)

* Refactor: remove __init__ meant for Python versions before 3.3
This does mess with a large amount of imports, as the system was being
misused to re-export submodules. This change is necessary if PyInstaller
is to work at all.

* Thanks Ruff
