This PR introduces simple filtering of duplicate housenumbers. Simple means that filtering is done withing the tile. Duplicates are defined as same housenumber, street, block_number[1]. Duplicates are usually caused by POIs. People like to add addresses to them. Most POIs have names so to prioritize addresses we pick features without names first. Formula is: `row_number() OVER(PARTITION BY concat(street, block_number, housenumber) ORDER BY has_name ASC) == 1`
