Link to public transport stops

[pietercolpaert]

Some entities of type osm:Node are also a gtfs:Stop. E.g., this one:

https://www.openstreetmap.org/node/2339852092 is same as https://data.delijn.be/stops/102827 (does not dereference, but can be found in this dataset: https://openplanner.ilabt.imec.be/delijn/Antwerpen/stops)

This way, routable tiles can become an interesting manner to also discover bus stops.

Automated mapping is possible by checking the osm tag ref:De_Lijn. For the bus stop in the example, the equals to 102827. Prefixing this number with https://data.delijn.be/stops/ gives the right identifier.

I propose to just use owl:sameAs here and anotate the node with an @type: gtfs:Stop.
