tinyAVR UPDI + SPI matrix keypad to i2c

Was impressed that the PCBWay 2-layer design rules support fine-pitch QFN parts such as the AVR ATTiny426. Board works great, and I look forward to trying out the UPDI functionality to use the newer, lower cost tinyAVR parts as opposed to the old SPI-based In System Programming variants such as the ATTiny88 (also included, as a backup).
