Add a new board - the Adafruit Macropad w/RP2040 (#191)

* add two variant files

* add trinkey and stemma friend

* add fast SPI transfer using pico-sdk blocks

* update makeboards.py for new variants

- STEMMA Friend RP2040
- Trinkey RP2040 QT

* run astyle on SPI library

* fix auto -> ssize type

* astyled

* woops ssizet != sizet!

* a nice day for a new board definition! this is a macropad with 12 keys, oled and rotary encoder
