[HLA] Using Python threads

[markgarrison]

@BitBob, have you seen this post already?

Third party libraries with HLAs

It should work if the user manually installs the package to that location, though coming up with an install location that will work on Windows and macOS/Linux will be challenging. Extensions installed via the marketplace are configured in the same way as local extensions at the Python level so there shouldn’t be any differences there.

I didn’t realize we included and tkinter files, I’ll look into what’s pulling that in later.

I recommend trying to pull these packages with your local python install. (we use 3.8, you may want to use that temporarily to maximize the chances of this working).
