Add discovered HVAC and PRESET options (#1177)

* Add discovered HVAC and PRESET options

This commit adds the HVAC Action Set and Preset Set that I've discovered my Bödenwarme Underfloor Heating thermostat to be using as detailed here: #1175

* Add HVAC mode and action sets for climate entities

These are the actions and modes as reported by the Magnum smart wifi
thermostat: https://www.magnumheating.com/product/remote-control/
