Hide element names in PCB
So little space for these anyways.

Adjust soldermask to pass freedfm tests
1. Fix new M2.5 holes by copying old ones.
2. Fix s-pwson-n6. Library footprint for this was fixed some time ago.

Switch to USB on the debug connector. Sadly, lose the LED.
This also adds current limiting resistors for the USB connection,
because there was plenty of space.

Add serial tx/rx to debug connector
Share tx with LED (will take some SW fun). The connector has GND at
pin 3, which is marked with square copper. The TX/RX pins are on one
side and the SWD pins are on the other. This was dramatically easier
to route than the alternative.

Add xtal for radio
The attempt to use the SoC to generate a reference for the radio
resulted in so much noise that neither receive nor transmit worked
properly.

Clean up partslists. Play with RF section.
Partslists now generate complete data from preferred parts.
RF section adjusted to avoid parallel inductors.

Add mounting holes on the other end by making the board longer.
I don't know if this is what we want, but it seems like it will make
the board easier to mount.

the spec.

Separate most of the passives with some solder mask
This should make them solder more reliably; it's still more cozy in
spots than I'd like.
