Add "Passive Cooling" to Heat Pump Status entity

[mhjansen79]

Currently the Heat Pump Status Sensor Entity includes the statuses of Hot Water, Heating, Anti Legionella, Standby, No Demand and Off, however there is also another status which is "Passive Cooling"

When the Heat Pump (Thermia Calibra Cool 7 WW) is in the Passive Cooling mode the status found through the integration is Off.

Thanks for a great integration!
