[issue44154] Optimize Fraction pickling

[Tim Peters]

Tim Peters <tim at python.org> added the comment:

Oh yes - please do. It's not just pickle size - going through str() makes (un)pickling quadratic time in both directions if components are large. Pickle the component ints instead, and the more recent pickle protocol(s) can do both directions in linear time instead.
