Compare PyInstaller, Nuitka and pyside6-deploy

[co-stig]

After each release at least some of the antivirus on Windows incorrectly detect Flowkeeper as malware. This is extremely annoying, as we can't simply go and release it automatically, and have to check via VirusTotal first, and then write a bunch of emails to remove the false positives. This might easily take a week.

I assume that different Python packers have different tolerances, and it would be great to compare them against each other. Also try with/without UPX. Also try to sign the "installed" EXE file.

So far I found the following options:

• https://www.py2exe.org/
• https://doc.qt.io/qtforpython-6/deployment/deployment-pyside6-deploy.html
• https://nuitka.net/pages/overview.html
• https://pynsist.readthedocs.io/en/latest/
• https://cx-freeze.readthedocs.io/en/stable/
• https://pypi.org/project/pyqtdeploy/
• Install a properly packaged Python as a dependency via NSIS, then install Flowkeeper dependencies via pip, then create a desktop link to run desktop.py -- basically build it from sources on install.
