Different OpenRailwayMap Styles

We currently only support one ORM style. It would be awesome to select the specific ORM style yourself.

This selection should be stored inside the pinia user storage

Which layers would you like to see added?
To be honest, I don't see any added value in any of the other ORM layers here. I only think the infrastructure layer makes sense for Träwelling.

Idk. Max speed might be of interest for some people
