XDA profile

Amazing project! It's wonderful to work with.

I'm building off the work of @kelvie (#87) to implement the XDA keycap style, since I needed them for a project of mine. I have a set XDA keycaps and calipers, so here's all the info:

The measurements I took. The keycaps are cheaply made and dimensions (especially the width of the keycap's base) varied from part to part. Some of these features (like the rounded corners) were difficult to measure accurately as well, so these are all the best approximations I could make.

The rendered keycap & keycap from which I took measurements.

Since XDA keycaps are all uniform as far as I know I've fixed the tilt and height to constant values regardless of the given row/column in the xda_row function. Yet it feels weird disregarding the given row and column to the function.
