Overloaded std::ostream operators for enum types are not being used by spdlog

[razorx89]

If someone tries to implement output operators for enum types (for much more informative output) then spdlog just implicitly casts the enum to int and gives the operator no chance. This can be fixed by changing the IsConvertibleToInt type trait.

enum { value = !std::is_enum::value && (sizeof(convert(get())) == sizeof(yes)) };

This is a C++ Format issue so I opened an issue there: fmtlib/fmt#232.

The issue has been fixed in C++ Format (fmtlib/fmt@6cff6d8), but the spdlog's copy has to be updated for this to have effect.

So how do i get this to work as the user?
cout << enum works but
spdlog::error("{}" My_ENUM} does not work
