This PR adding OSM ID to the lakes
OSM lakes are used from zoom 6
From zoom 0 to zoom 5 are used Natural Earth lakes.
- There is a new joining mat. view (`match_osm_ne_id`) contains which Natural Earth ID should convert to OSM ID. This logic is used to keep a consistent ID between switching between NE (zooms 0 - 5) and OSM (zooms 6 - 12). For smaller areas (not the whole planet), where are not available OSM lakes, the NE lakes keep their NE ID.
- There are also switch the final views to the mat. views - this should slightly increase performance (get rid of multipolygons).
- FIX typo for zooms 0 - 3 (`lakes` instead of `lake`).
