Add support for KlipperScreen

[eliasbakken]

It would be nice to run KlipperScreen as an alternative to Toggle. We should try and get a script for installing as a one line command, but for now here are some instructions to get started.

su debian

sudo apt install libgirepository1.0-dev
sudo apt install libcairo2-dev
sudo apt install at-spi2-core

cd /home/debian/
git clone https://github.com/jordanruthe/KlipperScreen.git
cd KlipperScreen
./scripts/KlipperScreen-install.sh

Issues:

• There is an issue running on top of Wayland which is that get_primary_monitor is not implemented, so get_monitor(0) must be used instead.
• On Wayland, it seems setting the screen height and width leaves a frame around the window. self.fullscreen() works better.
• On Manga Screen where the screen is in portrait mode, there is also an issue where the resolution is set wrong, so height/width might need to be exchanged.

The systemd file needs to be updated as well:

An install-script has been added which has been tested working.
