PCB adapter for Raspberry Pi to Hub75 RGB Matrixes

Since hand-wiring can be a little tedious, here are some PCBs that help with the wiring when using the rpi-rgb-led-matrix code.

* [Passive](./passive) is the simplest one, directly wiring the GPIO pins
  to the Hub75 IDC connectors for up to two parallel chains (for
  40 GPIO pin Raspberry Pis. Older 26 GPIO pin Raspberry Pis can connect
  to one chain).
* [Active](./active) Similar to the passive PCB, but does level
  shifting 3.3V -> 5V and provides convenient breakouts for I²C and serial.
* [Active3](./active-3) Like the active board, but supports three parallel
  chains with level shifting. Due to the additional amount of GPIO pins
  needed, I²C and serial can't be used (work in progress).

(Note: this is work in progress. I have not tested these yet. Once tested successfully, I'll provide an OSH-park link to order them).
