[wayland] Option to use the overlay layer

[draxil]

Feature Description

In some contexts (sway for example) flameshot appears behind a fullscreen window.

It would be nice if there were an option to make flameshot use the "overlay layer" (using the layer shell protocol) and thus be above normal windows.

Isn't that something a user should do with their window manager of choice? Window ruling should not be maintained and forced by the software.

Overlay layer stuff in wayland is usually on the the client side, for example wofi and rofi take advantage of the overlay layer. To my mind the case for flameshot is stronger, as flameshot really doesn't function properly in (for example) sway.

Since i moved to sway I have used window rules to mitigate the fact that flameshot didn't work as intended automatically (as it did in X11). But you can't achieve everything that way.

To my mind the layer shell protocol is here exactly for programs like flameshot to express "hey to function I really need to appear above the windows".
