[Python] Add detach() method to buffered streams

Details

    Description

      BufferedOutputStream::Close closes the raw file handle unconditionally. This may be undesirable in some circumstances.

      Some alternatives:

      • Do not close it
      • Only close it if the use_count of the shared_ptr is 1, so we know that no one else has a copy of the shared_ptr
