IDEA: Add Gas usage about pytado

[diamondo25]

I was actually looking into this, and the call to the Tado backend is as follows:

POST https://energy-insights.tado.com/api/homes/1234/meterReadings
{"date":"2023-03-07","reading":1584}

And the response is

{"id":"xxxx-f16b-4ef7-be0e-fef47cb061c0","homeId":1234,"date":"2023-03-07","reading":1584}

To get the current readings:

GET https://energy-insights.tado.com/api/homes/1234/meterReadings

{"readings":[{"id":"xxxx-f16b-4ef7-be0e-fef47cb061c0","homeId":1234,"reading":1584,"date":"2023-03-07"}]}

Maybe this can be easily be implemented to eventually get this into Home Assistant as a Service. Note that there's currently no "home" device of Tado, so maybe you'd want to either add that too, or bind it onto the Internet Bridge

Let's add this. It seems useful.
