SoE: minor typing and style fixes (#2724)

* 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
