ledmatrixctl depends on library that requires licence key

[sde1000]

When running ledmatrixctl, I see the following popup window:

If I click "Cancel", I can't continue — the program just exits, even if I'm trying to use it in command-line mode.

(I'm not willing to accept this licence. Further discussion: https://discuss.python.org/t/pysimplegui-now-requires-a-paid-license-opinions/48790 )

Moreover, the package for python-pysimplegui on Arch Linux fails to even build from AUR, because apparently they've also retroactively nuked existing pre-built packages. But the more I read about the project on that linked forum, the more I'm glad I couldn't run it on my machine.

I have a fork, that I'll submit a PR from soon. It removes all uses of PySimpleGui.

Some functionality is lost, and there is no GUI. But, it installs and works.
