Add nominatim integration

Thx Daniel for pointing in dm why my query didn't work.

It'd be nice if Ultra had Nominatim integration so that queries like this could work. Anything that requires looking such things up.

I run into this problem very often when I try to use Ultra, so it's one of the things that def keeps me on Turbo most of the time.

// This query finds all bicycle parkings within a 500-meter radius of any train station in Belgium.
[out:json][timeout:25];

// Define the distance in meters
{{radius=500}}

// Fetch the area for Belgium
{{geocodeArea:Belgium}}->.searchArea;

// Find all train stations in Belgium
node["railway"="station"](area.searchArea)->.stations;

// Find all bicycle parkings around these train stations within the specified radius
node(around.stations:{{radius}})["amenity"="bicycle_parking"];

// Print the results
out geom;
