    Summary: nanorand 0.5.0 - RNGs failed to generate properly for non-64-bit numbers

    Details: In versions of `nanorand` prior to 0.5.1, `RandomGen` implementations for standard unsigned integers could fail to properly generate numbers, due to using bit-shifting to truncate a 64-bit number, rather than just an `as` conversion. This often manifested as RNGs returning nothing but 0, including the cryptographically secure `ChaCha` random number generator..
