Hi, when I use the Lung CT Segmenter extension, I get the following error:

```auto
Failed to compute results: Command '['/Applications/Slicer.app/Contents/bin/../bin/PythonSlicer', '-m', 'pip', 'install', 'https://github.com/JoHof/lungmask/archive/master.zip']' returned non-zero exit status 1.

```

I tried with both ARM and Intel Macs and both got the same error, but it worked when I tried on PC.

Fixed by pip install 2.0.6 version of fill-void instead of the newest release
