It would not catch n:m with n and m set. I could do `auto lt = static_cast<LevelType>(static_cast<uint64_t>(lvlType) & 0xffffffff);` and use `case LevelType::NOutOfM`. But since there's a function isNOutOfM, I chose that for readability. But I don't have a strong preference, so if you prefer having a simple case, I can do that as well.
