e9067ac372 footprints: increase copper area for TVS diodes
We only had the bare minimum of copper, which didn't leave a lot of room
for the pick-and-place machine to err.  Increase the footprint size for
the TVS diodes.

0138d40853 hardware: footprints: enlarge some pads on ICE40
Enlarge some pads, to allow the PCB house to stay within tolerances.

They say that pads must be 0.23mm to ensure the laser doesn't escape the
pad.

ae5151f750 hardware: footprints: fix up Fab layer for all modules
Modify the `fab` layer so that it defaults to having footprint
identifiers, and places the designators in an area that makes sense.

97ccf7a350 hardware: footprint: make "nothing" through-hole
By making it through-hole, it won't show up in the pick-and-place file,
but it will show up in the BOM list.

66584765ff hardware: footprints: add new SON50
This has more copper, which might make hand-soldering easier.  Though
this PCB isn't going to be hand-soldered.

0bda71a0c8 hardware: footprints: add power regulator footprint
Add a footprint from KiCad for the power regulator we'll use.

It refers to a 3D file that doesn't exist, so we'll need to find that
first.

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.
