Method (how the database was made from OpenStreetMap)
1. Query the OpenStreetMap planet through QLever (https://qlever.dev/api/osm-planet)
   for every node, way and relation whose internet_access tag includes wlan or yes,
   taking the centroid of ways and relations, with name, amenity, shop, tourism,
   internet_access:fee, internet_access:ssid, access and internet_access:access.
2. Withhold places whose access or internet_access:access is private, no, members,
   permit, staff or students.
3. Keep: OpenStreetMap id, category (amenity, else "shop", else tourism), name,
   network name (internet_access:ssid) and an access code from internet_access:fee
   (no = free, customers = customers, yes = paid).
4. Cluster with supercluster and encode as Mapbox Vector Tiles (layer "hotspots"),
   grouped into the static packs under /data/tiles/.
