OSM Data Source: Support for 2023 tagging schema #391

Hello Johan, how are you currently generating the OSM data sources at osm.ev-map.app? Is it still my PoC script at https://github.com/ev-map/evmap-osm that runs nightly?

I'm asking because in 2023 a proposal for updating the OSM tagging schema was voted on and approved: https://wiki.openstreetmap.org/wiki/Proposal:EV_Charging_Station_Mapping This changes the tagging logic a bit, for example now charging stations should ideally be mapped as area, not as node.

The change brings some advantages for EVMap, for example now it has a tagging schema that includes chargepoints including EVSE IDs, which may be helpful for linking against chargeprice. However, the logic from the PoC is now too naive. As example, this charging station is micro-mapped as an area, but does not show up in your data JSON.

If the linked repo is still the latest version, I can try to come up with a PR that improves the querying logic.
