Enhancement: Adding "Since last refuel" endpoint data

[DerLev]

Hey there 👋
I've noticed that this lib pulls data for the last trip from VW but not from the "Since last refuel" section.

I already looked into the api the VW frontend uses and the endpoint for fetching that data seems to be something like this:
https://www.volkswagen.de/app/authproxy/vw-de/proxy/vehicles/<VIN>/tripdata/cyclic?gdc=myvw-mbb-prod&resourceHost=myvw-vcf-prod

With the data being structured like this:

{
  "data": [
    {
      "tripEndTimestamp": "2024-12-25T18:03:25Z",
      "id": "3632080251",
      "tripType": "cyclic",
      "vehicleType": "fuel",
      "mileage_km": 192,
      "mileage_mi": null,
      "startMileage_km": 20866,
      "startMileage_mi": null,
      "overallMileage_km": 21059,
      "overallMileage_mi": null,
      "travelTime": 292,
      "averageFuelConsumption": 7,
      "averageFuelConsumptionUnit": "l_per_100km",
      "averageElectricConsumption": null,
      "averageElectricConsumptionUnit": null,
      "averageGasConsumption": null,
      "averageAuxConsumption": null,
      "averageRecuperation": null,
      "averageSpeed_kmph": 39,
      "averageSpeed_mph": null
    }
  ]
}

I have a VW Polo from 2021, so I don't know how this endpoint behaves with an EV.

I will be looking into implementing this endpoint into this project, hopefully my rusty python skills can achieve that 😉

PR coming soon™️ - Help is always appreciated
