    [gnc-numeric.cpp] shortcut parsing num/denom as gnc_numeric
    
    The gnc_numeric is serialised as "num/denom" with no whitespace, and
    denom > 0. This function takes advantage of std::from_chars to parse
    it. The "num" serialisation is also optimised as a free side effect of
    this function.
