57b888ce0ebdeb34d866fd1511052fd740cc5ab8 fuzz: Add a test case for `ParseByteUnits()` (Chandra Pratap)

Pull request description:

  `ParseByteUnits()` is the only parsing function in `strencodings.cpp` lacking a fuzz test. Add a test case to check the function against arbitrary strings and randomized `default_multiplier`.
