/**
 * A more complex profile that generates vector tiles from Overture Maps data

 * To run:
 * - download a subset of overture data for a bounding box:
 * https://docs.overturemaps.org/getting-data/
 * - Run java -cp planetiler.jar Overture.java
 * - Open data/overture.pmtiles in https://pmtiles.io/
