- Introduced a new benchmark file `atoi_vs_from_chars_hex.cc` to compare the performance of various hex string conversion methods, including `strtoul`, `std::from_chars`, `fast_io::char_digit_to_literal`, and `fast_float::from_chars`. - Updated `CMakeLists.txt` to include the new benchmark executable `benchmark.0022.from_chars_hex` and set appropriate include directories and compile features.
- Introduced a new function `make_fixed_digits_numbers_buffer` to generate fixed-width decimal number buffers for benchmarking. - Enhanced the main function to include benchmarks for various integer parsing methods (e.g., `std::atoi`, `std::from_chars`, `fast_io::char_digit_to_literal`, and `fast_float::from_chars`) on fixed-width decimal substrings. - Updated output to use `fast_io::perrln` for consistency in error reporting.
