v1.8.0

This release brings everything up to tilezen/vector-datasource v1.8.0.

These filter functions were added for some POI filters:

• tz_estimate_parking_capacity
• tz_looks_like_service_area
• tz_looks_like_rest_area

Added these transforms:

• population_rank
• major_airport_detector
• add_vehicle_restrictions
• pois_direction_int

Added a lot of postprocessors that might be useful:

• remap - clean up some field values at zoom 13
• drop_names - used by landuse at zoom 13
• whitelist - approved values for certain fields, like road types.
• quantize_height - building heights
• clamp_min_zoom - keep features in higher zoom if they have a low scale_rank
• add_collision_rank - big one to sort label placement
• update_parenthetical_properties - removes feature if (closed) or similar at the end of the name

Not sure why the runtime and bytes have increased. A lot is different.
