[openstreetmap/openstreetmap-website] Antimeridian map data display (PR #6320)

[mmd]

This PR enables map data display across the antimeridian. It splits up the /map request into two requests if needed.

Depending on the current map center,  cloned nodes and ways with +/- 360 offset are added to the list of features. This is described in more here: https://stackoverflow.com/a/54709437/3501889
