Matching strings with DeviceMatch String isn't possible, compare /data/kamvas-pro-13.tablet with the evtest listings for Kamvas Pro 24

/dev/input/event13:	Tablet Monitor Pen
/dev/input/event14:	Tablet Monitor Pad
/dev/input/event16:	Tablet Monitor Touch Strip
/dev/input/event17:	Tablet Monitor Dial

I'll create the tablet file after #610 is fixed.

libinput issues

Some inputs are not recognised on this device, see this issue.

[Eckoa]

I created a tablet file and svg hacked together from the kamvas 13 file (im not great with inkscape), Im unsure as to how to set the buttons as being left vs right of the display with the EvdevCodes or if they should all be in just a large list. Currently Digimend and libinput are waiting on a patch for the buttons/touch strips to all work (as can be seen in the above mentioned issues) so This is only for the left side buttons. It includes the touch strips but the obviously wont work at the moment.

or if they should all be in just a large list.

IIRC the EvdevCodes is in the order A;B;C;, the location doesn't matter. So one large list.

[AesaraB]

It might be better to add further comments about the actual files in the draft pr

@Eckoa this might be more a thing for future reference, as I've created the new SVG file, but SVGs are actually at their core fairly simple XML files. Go ahead and open a couple of the layout files in a text editor.
