Implicit conversion operators and enums was removed for parity with std::format (https://github.com/fmtlib/fmt/commit/fce74caa15b24cbc0fcafe4706692cb06cb0b815).
HRWrap now allows HRESULT to be formatted, giving useful information beyond "it failed" or a hex code that isn't obvious to most users. This commit does not add any uses of it, though.
