Add APDS9960 driver

[QuirkyCort]

This is a driver for the APDS9960. https://github.com/QuirkyCort/IoTy/blob/main/public/extensions/apds9960.py

Compared to the current driver listed on awesome-micropython, this one adds simple gesture detection (up, down, left, and right).

This driver was written for the IoTy project (...a web-based blocks to Python system, similar to BIPES), so it doesn't have it's own repository.
