Saswell T29UTK: changes based on new information.

From issue #45

- uncouple power and hvac_mode
- dps 112 is the configuration setting of the thermostat:
    1. 1 or 2-stage cooling
    2. 1 or 2-stage heating
    3. 1 or 2-stage heating and cooling
    5. 1/2 speed/compressor heat pump with 1 or 2 aux outputs

In config 1, the HEAT mode is not available, in config 2 COOL is not available.
Probably another dps is the aux switch for the last option.
