Following up from work in #583 which gave us significant feature count reduction and file size savings...

QA for that work revealed that at low zooms we still have individual tile features for national_park features but I expected to only see merged "generic" polygons within the kind. This issue tracks also merging those features.

Here's a view in the USA (example tile 4/2/5):

the different colors show individual features with unique IDs

I think this is because even though the name is removed, the unique ID is still present, which then prevents the merge?

Here's Point Reyes in 9/81/197:

the different colors show individual features with unique IDs
grey colors are for landuse polygons that have been merged
