This PR collapses housenumber values into the form min(housenumber)-max(housenumber) for cases where housenumber is a semi-colon separated list. If the list is all numbers, the bounds are the smallest and largest numbers. If the list includes non-numeric characters, it falls back to the first and last values in the list.
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`
