✨ Improve support for tile widgets

[anarion80]

This is an attempt to improve tile widget support. Tile widgets look as follows:

{
            "id": 1007,
            "parentId": 0,
            "type": 6,
            "menuId": 2061,
            "orderId": 5,
            "visibility": true,
            "params": {
                "description": "Universal status with widgets",
                "statusId": 1,
                "iconId": 87,
                "widget1": {
                    "txtId": 938,
                    "value": -40,
                    "unit": 7,
                    "type": 1,
                    "params": [
                        0,
                        0,
                        0,
                        0,
                        0
                    ]
                },
                "widget2": {
                    "txtId": 1041,
                    "value": 469,
                    "unit": 7,
                    "type": 9,
                    "params": [
                        0,
                        0,
                        0,
                        0,
                        0
                    ]
                }
            }
        },

They are of type 6 and have two widget objects under params key: widget1 and widget2. The API is lacking in this area, so only through users submitting their logs we are building a complete picture.

Till now we have been treating all "type": 6 tiles as Central Heating Temperature type and using only widget1. Now we know that this type represents not only temperature, but also other entities like pumps, and this seems to be determined by type key under widget. So far we deduced the following:

type	Widget type	Comments
0	Set room temperature if "unit" != -1 or binary switch/contact if "unit" == -1 ??
1	DHW Pump Temperature	widget1 is Set Temperature and widget2 is Current Temperature, but seems to be no way to know that from API
2	Collector Pump/Modulation (percentage)
9	Temperature (CH/DHW/Room)

Both above types are available in the emodul DEMO account.
