ESPhome: Treatlife Smart Dimmer Switch DS02S

I finally took the time to convert the Treatlife Single Pole Smart Dimmer Switch (DS02S) to ESPhome after a bunch of searching and trial and error I finally have a good configuration that gives me all of the same control and options just without the connection to Tuya/Treatlife.

I purchased the DS02S in July 2022, the version that I received has a board version 2.1 with a date code of 2020/06/23. It does have the WB3S module and the Nuvoton (TuyaMCU) controller. I was able to use tuya-cloudcutter to load ESPhome to the board. Below is the YAML file I have loaded and operating on this switch. Some of the text sensors might be too much information so you can always comment it out.
