New extension manager and issues with corporate certificates

This seems to work. At least it is finding the filename correct, I do not know how to write

>>> import wget
>>> url = "https://slicer-packages.kitware.com/api/v1/file/613b26b1342a877cb3bee81e/download"
>>> filename = wget.download(url)
>>> filename
'30168-win-amd64-SlicerMorph-gitf70c039-2021-08-20.zip'
