Release 0.2.2

• Amalgamate: fix include of <charconv> (see rapidyaml#445).
• Add C4_MINGW (PR#139)
• Annotate c4::handle_error() with [[noreturn]] (PR#137).
• Add bool from_chars(csubstr s, fmt::overflow_checked_<T> *wrapper). There was already a function receiving &wrapper, but *wrapper was missing for use with generic code.
• Ensure posix_memalign() is never called with bad alignment values (PR#138)
• Update fast_float to v6.1.1 (PR#136)
