macros `FASTFLOAT_ONLY_ROUNDS_TO_NEAREST_SUPPORTED` if you only need `FE_TONEAREST` rounding mode in the parsing; this option
also improves performance a bit and reduces code size. In the high-performance example, I also use the [fmt library](https://github.com/fmtlib/fmt), which also
supports all C++ standards since C++11. I also recommend using `string_view` everywhere if it's possible; it's available
