Daniel Lemire 8e3e876b2e Add optional support for digit separators and cpp prefixes (#369) ... Rebased onto current main. Adds optional support in from_chars_advanced to skip a configurable digit separator (e.g. ') and to skip standard cpp prefixes (0x/0X, 0b/0B) before decimal parsing. Reconciled with main's straight-line-unroll optimization of the integer-part scan: the fast unrolled path and loop_parse_if_eight_digits fast path are preserved for the common no-separator case; separator-aware loops are used only when a digit separator is configured. Original work by zaewc (PR #369), squashed during conflict resolution.		2026-06-05 22:18:00 -04:00
