  rs274ngc: parse numbers with std::from_chars

read_real_number built a std::string and a std::stringstream for every number
in a program, and read_integer_unsigned handed the digits it had already
delimited to sscanf("%d"). std::from_chars needs neither, and is
locale-independent where the stream was not. Accepted syntax, parsed values
and both error messages are unchanged, except that a magnitude too small for
a double, and a line number too large for an int, are now parse errors.
Parsing a 13.7M line program is 2.1x faster.
