zufast: Fast Portable 'C' Primitives for Parsing and Formatting Data

A header-only library of small, fast, portable 'C99' primitives for converting external text and bytes into native values and back: correctly rounded number parsing, shortest round-trip number formatting, ISO 8601 dates and timestamps, booleans, universally unique identifiers (UUIDs), hexadecimal and Base64, 'XXH3' hashing (from 'xxHash'), half-precision floats, endian helpers and UTF-8 validation. Other packages use it through 'LinkingTo' alone; the 'R' functions exist to test, benchmark and demonstrate the 'C' layer.
