Esphome example for the uart based GY-906 optical temperature sensor.

I created this as I could not find an example anywhere. I used other UART and sensor examples to form the esphome basics... The implementation to read the GY-906 is very basic, and my own derivatives. IT works reliably

1. Copy the GY-906.h file to your config/esphome folder. You can do this in many ways. SAMBA share being one method.
2. Create a new entitiy in ESP home, and modify/replace the yaml file with the example fireplace_temp.yaml from this repo.
3. Modify the neccesary sections to match your environment.

Enjoy.
