Dear Maintainer,

1) added large file [29.7GiB] to share
2) hit 'start sharing'
3) the progress bar seemed to get stuck, and a warning was given

/usr/lib/python3/dist-packages/onionshare/tab/mode/share_mode/threads.py:40:
RuntimeWarning: libshiboken: Overflow: Value 33282126421 exceeds
limits of type  [signed] "i" (4bytes).
  self.mode._zip_progress_bar.update_processed_size_signal.emit(x)
OverflowError

the compression itself seems to have worked, and the file seems to be
shared but this warning still
was outputted.
