Can't save the silence clip

[Tschipp]

When I try to save the silence using the --save-silence argument, I get this error:

Finding gaps...
Traceback (most recent call last):
  File "video-remove-silence", line 138, in <module>
    silences, including_end = find_silences(audio_file.name)
  File "video-remove-silence", line 118, in find_silences
    frames = wav.readframes(end - start)
  File "C:\Users\USER\AppData\Local\Programs\Python\Python38\lib\wave.py", line 243, in readframes
    data = self._data_chunk.read(nframes * self._framesize)
  File "C:\Users\USER\AppData\Local\Programs\Python\Python38\lib\chunk.py", line 136, in read
    data = self.file.read(size)
  File "C:\Users\USER\AppData\Local\Programs\Python\Python38\lib\chunk.py", line 136, in read
    data = self.file.read(size)
TypeError: argument should be integer or None, not 'float'

I went and took a look and it seems that this is where it fails:
frames = wav.readframes(end - start), because end - start is a float. I tried casting it to an int but that didn't work for some reason.
