ATMega2560 PCB fixes and updates
...
- add additional key matrix connector (for custom matrix including Apple 2)
- Fix bypassed diodes. Diodes on rows 8-15 should have been
- jumpered (bypassed), but instead were standard diode footprints.

Move LED current limit resistors to keyboard PCB
...
For better matching of current limit resistors to LEDs, the resistors are moved
to the keyboard matrix PCB, where they can be tuned for maximum brightness (at
100% duty cycle). This allows consistent keyboard brightness when a single
interface PCB is swapped between keyboard matrices.
