WIP: More Windows-compatible

[gustaphe]

The main thing in the way of Windows compatibility is using shell=True, which seems to be recommended against for security reasons anyway.

A few things are not yet fixed:

• Archiving acts weird, I think it expects slash-separated file names inside tar files but receives backslashes
• Matlab doesn't yet work, it still gets called with --version for some reason
• Probably a bunch of things I haven't tested yet

Anyway, figured I would offer up what I've found so far. Is this too agressive?

This works. It currently uses Matlab >=2014's matlab.codetools.requiredFilesAndProducts instead of depfun which was deprecated. Also Matlab >=2019's -batch to run headless. That part should probably be configurable as it is breaking.

There are a couple of details I have not worked on because I don't quite understand them, like LaunchMode.generate_command.

Archiving I cannot get to work, whether in Matlab or Python. That's probably an OS issue.

Thanks @gustaphe - I've dug out an old laptop and asked our IT department to update it to Windows 11 and install MATLAB, so I should be able to test this soon.
