Add compatibility with recently added ByteArray to base:

* Switch to using `ByteArray` for type class implementation instead of
  `ShortByteString`
* Add `unsafeUniformFillMutableByteArray` to `RandomGen` and a helper function
  `defaultUnsafeUniformFillMutableByteArray` that makes implementation
  for most instances easier.
* Add `uniformByteArray`, `uniformByteString` and `uniformFillMutableByteArray`
* Add `uniformByteArrayM` to `StatefulGen`
* Add `uniformByteStringM` and `uniformShortByteStringM`
* Deprecate `uniformShortByteString` in favor of `uniformShortByteStringM` for
  consistent naming and a future plan of removing it from `StatefulGen`
  type class
* Expose a helper function `genByteArrayST`, that can be used for
  defining implementation for `uniformByteArrayM`
