  C++ integer-to-string conversion benchmark

I considered using this method in {fmt} and found that its drawback compared to some alternatives is that it doesn't give you the number of digits in advance which means that you end up doing a copy. So often an optimized version of countlut from https://github.com/miloyip/itoa-benchmark performs better.

  Fast integer to ascii / integer to string conversion

I know, I was just being lazy 😏. This is also why itoa_always_10_digits performs the best in the benchmark, while it is in fact horribly slow for realistic data. If you care, here is a benchmark with a more realistic data: https://github.com/jeaiii/itoa.
