parse_double_strtod()

std::optional< double > tmk::detail::parse_double_strtod ( std::string_view s )

strtod_l with the "C" locale, restricted to the grammar of std::from_chars(chars_format::general): strtod also takes leading whitespace, '+' and hex, which from_chars does not.

Correctly rounded on glibc and Apple's libc, so it gives the same double as from_chars; tests/test_units.cpp checks that wherever from_chars exists.

< strtod needs a terminated string

strtod also sets ERANGE for a subnormal result, which from_chars returns; only overflow and underflow to zero are result_out_of_range there.
