Subject: [PATCH] suppresses `-Wuseless-cast` for static_cast<char_type>('\0')
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

needed in case 'char_type' is 'char' (common on Linux but rare on Windows?)

```text
[..]/magic_enum.hpp:275:114: warning: useless cast to type ‘using magic_enum::char_type = using std::basic_string_view<char>::value_type = char’ {aka ‘char’} [-Wuseless-cast]
  275 |   constexpr static_str(string_view str, std::integer_sequence<std::uint16_t, I...>) noexcept : chars_{str[I]..., static_cast<char_type>('\0')} {}
      |                                                                                                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
