Fix and extend implementation of `BytesIOWrapper` (#2853)

* Fix implementation of BytesIOWrapper to make it more complete, more useful, and compliant with Python's BufferedIOBase and BinaryIO interface.
BytesIOWrapper can now also wrap a TextIO Unicode file, or a StringIO, as well as the original wrapped str.

* Add remaining missing methods: truncate, flush, isatty, fileno.

* Catch OSError in BytesIOWrapper on base stream isatty() and fileno(), throw this error when expected when corresponding functions are invoked on the Wrapper.
