Rotenso RONI IR35WI: merge with identical Royal Air Conditioner
Not sure why the original report did not match, but they do now with
subsequent revision of the Royal config to match other models.
One minor difference, fan speed auto is "0" in Royal config, but was
"4" in Rotenso. Based on the history, it was swapped from "0" to "4" when
the fan speed order was found to be reversed, but the commit comment notes
that I wasn't sure about that part. Since everything else is identical,
including the backwards fan speed mapping, likely this is too, so "0"
matching the Royal config seems appropriate.
