Dummy monitor

[raldone01]

This pr is an extension to #421. It adds a working dummy_monitor script. It currently requires an edid file. I would like it to work with just <width>x<height>@<fps>.

[pradyvrp]

does this support wayland?

[raldone01]

What do you mean exactly?

The dummy monitor program itself has no issue with wayland as it uses PySide6. evdi should also not have any issues with wayland as I have used a displaylink docking station yesterday with plasma wayland.

But just try it out?

~Hey, im wondering what version of python and pyside6 you are using, since I am getting the following error:~

Oh I just relealized this is might be casued by a mismatched pyevdi version - Could you please update this pr the latest?
