Special modes mapping

NWT's dehumidifier supports continuous mode and dry cloth mode, which is absent in HomeKit. The plugins maps those modes into available controls as a work-around.

When you set target dehumidifier threshold to 0, the dehumidifier will turn on continuous mode.

When you set fan speed to the maximum, the dehumidifier will turn on dry cloth mode.
