ENH: Add KIT-157 layout

I generated the layout using `layout._auto_topomap_coord` and made some minimal manual changes. I have no idea what the box size should be, and the scaling is arbitrary -- let me know if you have tips on finding the size of the box. (As far as I can tell we never use the box size anywhere?)

I'm attaching a screen shot of what the layout looks like. (Is there an existing easy way to generate this kind of plot btw or should I maybe add this code to the repo?)
