* SoE: fix typing for tests
* SoE: explicitly export pyevermizer
To support loading the module from source (rather than module) we import
pyevermizer from `__init__.py` in other files. This has been an implicit export
and `mypy --strict` disables implicit exports, so we export it explicitly now.
* SoE: fix style in patch.py
* SoE: remove unused imports
* SoE: fix format mistakes
* SoE: cleaner typing in SoEOptions.flags
