Enhancement: Add Heating-cooling unit

[ticaki]

The device is currently available in the iobroker:
https://github.com/ioBroker/ioBroker.type-detector/blob/master/DEVICES.md#air-conditioner-aircondition
to control an air conditioning system.

The device as such would not be bad. However, Apple, for example, offer a device which, in addition to the temperature that can be set for cooling and heating, also has an automatic mode in which you can set the target temperature for cooling and heating. In other words, a temperature at which the air conditioning system lowers the temperature and a temperature at which the central heating heats the room. There are no roles for this.

At the moment, my states look like this:

If you like, I can make a short version tonight.
Long version:

target_temperature is used when heating or cooling is selected - the other two when automatic is selected.

@ticaki That shoukd work, beside homekit_CurrentHeatingCoolingState ... thats it not writable and just a value ... so it can nt be controlled ... makes that sense?
I would expect it writable and ideally with level.mode.airconditioner

@Apollon77

TargetHeatingCoolingState: here you control the appliance by setting it to: Heating, Cooling, Automatic or Off

CurrentHeatingCoolingState: Here the appliance reports that it is currently heating, cooling or idling because the current temperature does not require heating or cooling.

EDIT: CurrentHeatingCoolingState is nice to have :)

TargetHeatingCoolingState ... ok, passt ... ausser die Rolle .. änder die mal, dann wird später die erkennung tun, sonst fehlt der Mode
