Add Husky Lens drivers

[QuirkyCort]

This is a driver for the DFRobot Husky Lens. https://github.com/QuirkyCort/IoTy/blob/main/public/extensions/huskylib.py

The Husky Lens (https://www.dfrobot.com/product-1922.html) is a camera module that can do some onboard machine vision tasks and returns the results in either UART or I2C mode.

The driver is based on the official Python API (https://github.com/HuskyLens/HUSKYLENSPython), but heavily modified to work with micropython and fix a few bugs.

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.
