For fixing Parking not appearing on Sport Centres
https://trac.openstreetmap.org/ticket/4419

This is because we render landuse (which includes parking areas) before Sport Centres.

Split the layer for landuse and removed parking.

Added parking-area separately and placed just after sport centre rendering.

Landcover changes

Removed parking from and added it as a separate module/#parking-area
