union ocean regular squares into complex polygon (#1021 )

The ocean layer (table osm_ocean_polygon insert by `make import-data`) is made from squares that have a 10m buffer. 

This creates extra geometry in vector tiles as:

Union of full ocean squares should decrease the size of the water layer.

there are 8042 polygons (squares, 5 points, more then 100km<sup>2</sup>), which was reduced to 22 polygons - 1184kB vs 40kB respectively. 

In mbtiles should be the size reduction even more significant, due to the creation of more polygons based on a 10m buffer of each square.

NOOP water - Move updating sql into separate file (#920 )

Use `update_water.sql` for all queries that update db
to be consistent with the other layers.
