Only pulls in 1 station per postcode

[tjorim]

Setting up this integration only seems to set up a single device with a single entity.
Not sure if feature or bug.
I don't know what the logic here is: does it currently get the cheapest station, the first station in the list?
Feature request: would be nice if it adds all stations (entities) per postcode (device).

for now, indeed the closest and cheapest is shown in the sensor, but internally all stations in the neighborhood are already retrieved. I plan to add extra sensors soon to also provide info on the cheapest station in the neighborhood of the postal code.
