Add support for AS7341 in firmware

[Jerzeek]

Someone proposed adding a color sensor to get more information about the plastic sample. we settled on the AS7341 (thanks Loki!), for testing we bought the Adafruit breakout board. The DB2.1 already has a QWIIC connector so assembly is simple, we just need to implement it in the firmware! This can be as simple as adding the example code to the platformIO environment
