On some compiler enum-aliases not supported, [for example Visual Studio 2017](https://github.com/Neargye/magic_enum/issues/36).
On some compiler enum-aliases not supported, [for example Visual Studio 2017](https://github.com/Neargye/magic_enum/issues/36), macro `MAGIC_ENUM_SUPPORTED_ALIASES` will be undefined.
It is possible to check whether enum-aliases supported using a macro `MAGIC_ENUM_SUPPORTED_ALIASES`.
```cpp
enum Number {
one = 1,
ONE = 1
};
// magic_enum::enum_cast<Number>("one") -> std::nullopt
// magic_enum::enum_name(Number::one) -> ""
// magic_enum::enum_cast<Number>("ONE") -> std::nullopt
// magic_enum::enum_name(Number::ONE) -> ""
