* 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 as suggested by beauxq
