[jposada202020]

Changes

1. Adding properties for critical temperatures, and hysteresis
2. Small doc changes

Expected Results

To achieve this raise the sensor temperature over 28.1 Celsius

Looks good to me. Tested successfully with:

Adafruit CircuitPython 7.1.0-beta.0 on 2021-11-12; Adafruit PyPortal with samd51j20
Board ID:pyportal

Thanks for the new functionality @jposada202020
