RationalParsing class

A utility class for parsing strings into Rational objects with round-trip support. Unlike Rational.parse, which only handles integers, decimals, and scientific notation, this class can parse fractions (e.g., "7/4") produced by Rational.toString, ensuring compatibility with its output format as well as mixed fractions (e.g., "1 3/4").
