Cannot open VTK output file

@daoney @DillonLabban @waleedfaried @Y_Guo (and anyone else who’s experienced the VTK problem)

I just uploaded a new version, 21.1.2, to the website which should fix the VTK installation issue. Please give it a try and post here if you have any further problems.

This problem is due to some recent changes in Anaconda (an update to libtbb left VTK without one of its needed dependencies), and we didn’t see it here because I was using a slightly older Anaconda version.

Thanks for the bug reports and the patience.
