Add a configuration option to set a tablet as a relative input

[Eragonfr]

I have a Wacom intuos M Bluetooth, and i like using it as a relative input.
I haven't view any sway configuration option to set that.
It's possible to add that into sway ? Or into wlroots ?

libinput does give us relative coordinates for tablet events, but sway isn't hooked up to use it.

https://github.com/swaywm/sway/blob/master/sway/input/cursor.c#L440-L469
(struct wlr_event_tablet_tool_axis has that dx and dy as a member).

I'll admit that the input code would be the part I'm the least familiar with, but I don't think it would be that hard for someone to add support for that.

Progress with the issue #2288 ?

I'm not a good dev, and I don't know how i can add my modification in a good way. I want to add an option similar to option "Mode Relative"(from X libinput configuration) into main sway configuration file; so users can choose between relative and absolute input.
Do you have any idea how I can create that ?
