This appears to be kicad deciding to rewrite the whole file for no
particular reason.

84990ef80e hardware: pcb: redo dbg numbering and add silk to rpi header
Redo the numbering for the dbg pins.  While we're at it, add some silk
to the Raspberry Pi header so that we know what we're looking at.

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.

70c3c758da hardware: pcb: update footprints and 3d models for pin 1 marker
Update the footprints so that the pin 1 marker is actually visible by
using silk where possible.

37ff812b49 hardware: pcb: replace "text" with "value" for buttons
Previously, we used text to display the "5" and "6" designators for the
physical buttons.  Replace this with a value of "5" and "6", and remove
the extra text.

Additionally, display "SW??" under the switch, to make hand-assembly
easier.

Do the same thing for the "Reset" button.

12eed495f2 hardawre: pcb: remove 3D models for headers
These are nominally DNP, so remove the 3D models to make the render more
accurate.

62dab34633 hardware: pcb: repour and connect wire in kicad
The `VCCPLL` line was listed as "Not Connected" in KiCad.  Reconnect it,
even though it was already connected.

74963bd034 hardware: pcb: fix virtual and smd designation
Some components were getting added to the BOM that shouldn't have been,
and some were missing from the pick-and-place file.

Update the `Placement Type` to be accurate according to assembly.

25b662e6fb hardware: pcb: re-route USB after flipping the footprint
It looks kinda janky, but it's better than ripping everything up and
starting over.

e91896a8fb hardware: pcb: loosen up the ground plane / 5V some more
Move some vias around to get the 5V plane more breathing room.  Add a
small pour to give more copper and stabilize the net.

e48d836372 pcb: remove usb silk, add more 5V vias
Add more 5V vias near the 1.2V regulator, and replace a manual trace
with a copper pour.  This will increase the amount of copper going to
both the 3.3V and 1.2V regulators, which should improve stability.

While we're at it, remove an errant silk artifact on the USB connector.

Add a note indicating the PCB thickness and color.

Also, move the drill origin to the lower-left corner, to aid in machine
assembly.

12afe3aed1 pcb: add more silk, fatten up ground traces
Add more silk, indicating website and other info.

While we're at it, move some traces around to give more copper area, and
drop some more vias to improve ground performance.
