Speed in ifan03 yaml is wrong

[kendall15]

The speed listed is Sonoff_iFAN03_buzzer.yaml is listed like a constant (LOW/MEDIUM/HIGH) however they are not recognized as a constant. I am not sure if constants can be used in the yaml. In Sonoff_iFAN03.yaml the speeds are listed as 1, 2 , and3 however it gets translated to a float and scaled at some point. It looks like 60,90,100 works as desired.
