Support for 'quiet' mode in COOLIX protocol

[gomezguillermo]

Version/revision of the library used

v2.8.6 or 'master' as at 1st of July, 2024.

Describe the bug

Support to implement quiet mode in COOLIX protocol. I got a Samsung AC model ar12txhqbwkneu. I can control nicely my AC, IRremoteESP8266 reports my remote control uses COOLIX protocol, all works except 'Silence' key, according to the manual when user press that key it lower the compresor frequency and fan become lower than minimum fan speed, it seems like a special mode.

To Reproduce

Press 'Silence' key, IRremoteESP8266 interpret it like 'Dry' mode and set the temperature to 30C
