Add support for Atlantic Thermostat PRE (for electric underfloor heating)

[0rax]

This PR adds support for the Atlantic Thermostat PRE used to control Domocable / Soleka based electric underfloor heating.

What changed

This PR adds support for Thermostat Thermal Zone (TZHONE) devices as well as update the logic for the detection of available heating/cooling device per ROOM entity (modelID between 557 and 561).

In order to better detect if an AC or an underfloor heater is available in a ROOM, I added logic that checks all the child devices in a room and check their type using their IDs (UI_1, THZONE_1, ...), favoring ACs first as they are usually reversible then thermal zones and only exposing the support modes. I have also kept the original logic as fallback in case this logic doesn't work with other models.

To do so, I had to update the get_model_infos to also receive the device tags so I can access the iothubChildrenIds tag needed for the logic.

These changes should be pretty generic to support other types of underfloor heating system if they expose a THZONE device and adding more logic based on different childID prefixes should be pretty straightforward if a new system exposes a new type.

Usage

This requires all thermostat to be linked to the Atlantic Cozytouch App through the Cozytouch Hub and assigned to a room.

Then when adding the Cozytouch integration to Home Assistant, you will see a set of THZONE (on per thermostat) and ROOM (one per room defined).

The THZONE itself will not expose any useful data except connectivity information, so you may not need to add it to HA.

Each ROOM will allow you to control the Thermostat directly from HA and expose only the implement heating components.
