No module named 'termios' on Windows

[Wayne Bowie]

Describe the bug
On first load of any file I get this error message and from there no commands seem to do anything
I'm on Windows 10 using C# and the dotnet test runner

error caught in notification handler 'C:/Users/wayneb/AppData/Local/nvim-data/site/pack/packer/start/vim-ultest/rplugin/python3/ultest:function:_ultest_update_positions [['Jobs.Tests\\Controllers\\JobTrackerControllerShould.cs']]'

I have this very same issue

[Rónán Carrigan]

Same as #71, happy to take a PR to fix this but I don't have a windows machine to develop on. Closing to keep discussion in one place
