feat: Use the enhanced DEM to improve contour lines of topo maps #3

Most contour lines currently use SRTM (at the exception of Maki's maps Bugianen and Sorbetto) Especially it would make sense for OpenTopoMap. Hill-shading is also possible but probably would have less of an impact.

Swisstopo contour lines setup

z¹	major	minor
16	100	10
15	100	20
14	100	20
13	200	50
12	500	100
11	ø	ø

¹ "z" here is the equivalent xyz slippy map zoom-level after dezooming by 1-level to compensate for the retina resolution of the current default tiles on map.geo.admin.ch)
