Low zoom levels #2

Tiles at low zoom levels must to respond to the curvature of the Earth, while their minimal scaled topographic range often yields only two triangles covering the entire tile. For zoom levels less than 5, we currently fall back to a basic height field, but we should ideally have a method that subdivides triangles to densify the mesh to a certain threshold size.

We have solved this for now by bundling our own version of Martini that allows specifying maximum triangle size, this seems to work pretty well!
