6a392e57d2 pcb: rework pcb with correct footprints, add tvs diodes
Add TVS diodes, so we make sure they work.

Also, rework the PCB so that the clock actually functions now.

The footprint was backwards, which lead to some serious performance
issues.

f3315b58d8 pcb: add our own copies of 3d models and footprints
The Kicad default footprints seem volatile and unreliable.  Going
between two machines that both have "Kicad 5.0.0" installed results in
incompatibilities because KiCad has renamed their footprint libraries.

Also, for some reason it's going to Github to get footprints instead of
using local copies.

Copy every model and footprint we use into a local tomu-fpga.pretty.
This lets us ensure we can work offline, and also allows us to modify
footprints, e.g. by adding a "Pin 1" marker.
