* Worked on ESP32 dimmer with Zero cross
Until now the ESP32 does not support zero-cross dimmer. I take a sneak how they did in in ESPhome and adapted the approach to TASMOTA. At the end it works that smooth that likely i will change ESP8266 either so we have a common code. Currently ESP8266 is not touched.
There is a minor issue with savedata == default. When changing the dimmer value the interrupts get stopped during write of the config data to flash.
* ESP8266 Dimmer added
Worked all so well and the code is much smaller. There is no need for reconfiguration on existing users. But there are settings not needed anymore. Will work on the documentation. Anyhow existing installations can upgrade without hickup
