We manually use the "File -> Plot" function because KiBot only
exports the first page (despite `all_pages: true`).

The positions have an offset on the X axis so this is still not quite
right. The positions are the same as in the previous files so this
is weird.

We don't have a dedicated channel for S1 so that's the best that
we can do.

Including a "cheap" knock-off of ringclock (and even the idea to
put it on this board was stolen from fxk8y *g*).
