* Added description of some UPK keys
* More keys described.
This time by experimenting on my PIR-enabled lamp.
Motion is reported correctly via GPIO defined as pirin_pin.
I am also trying to set the PIR sensitivity by applying PWM to the pirsense_pin, and I _think_ it works. More experiments are needed.
* Add UPK2ESPHome link, reformat table
* Add descriptions from BK7231N SDK
* Update docs/resources/tuya-pin-config.md
* Corrected description of cwmaxp
* Description of ambient light sensor values
