Visualize OSM Ways data on a Map

[arindam1993]

This PR adds an additional logfile in the /logs folder, called ways_dump.ldgeojson thats a newline-delimited GeoJson of all the OSM Ways in the graph cache.

This dumpfile can be converted to a visualizable PMTiles tileset using

tippecanoe -zg -l ways_dump -P -o out.pmtiles --drop-densest-as-needed ways_dump.ldgeojson

I also added a webpage to visualize the data.

All the params are in there, here's an example of a OSM Way geo-json-ifield:

}

Anything in the properties can visualized on the map for debugging.
