create tiles from overture data

1. Copy the Overture Parquet dataset to your local machine to overture dir: Use these docs. You don't need Microsoft Synapse or AWS Athena.
2. Install DuckDB and run this script:

COPY (select json_extract(bbox,'$.minx') as x,
      json_extract(bbox,'$.miny') as y,
      json_extract_string(names, '$.common[0].value') as name,
      json_extract_string(categories, '$.main') as category_main,
      from read_parquet('overture/theme=places/type=place/*')) TO 'pois.csv' (HEADER, DELIMITER ',');

3. Feed pois.csv into felt/tippecanoe:

tippecanoe -o overture-pois.pmtiles pois.csv -M 80000 --drop-densest-as-needed

Bob's your uncle!
