Set minNativeZoom and maxNativeZoom for a map

This is similar to https://github.com/umap-project/umap/issues/103, but for the values.

• maxNativeZoom https://leafletjs.com/reference.html#gridlayer-maxnativezoom
• minNativeZoom

They allow to set a maxZoom for the tiles (that is the "native" value) independent from the maxZoom for the viewer.

Example:

• https://supaplexosm.github.io/strassenraumkarte-neukoelln/?map=osm#21/52.48146/13.44826 allows to zoom in further than 19.
