Integration of better data source for elevation bitmap about streets-gl HOT 5 CLOSED

LIDAR data is great, but not for this application. Elevation data needs to be processed so that it represents only terrain without buildings.

There is also https://opendem.info which also offers bathymetric data to enrich the seaside ;-)

Frankfurt Flughafen, on the other hand, looks quite bumpy: https://streets.gl/#50.04088,8.57643,11.75,228.00,3998.31

It seems like arcgis has a free elevation layer: https://www.arcgis.com/home/item.html?id=58a541efc59545e6b7137f961d7de883
It's hard to tell if the quality is better than whatever Mapbox provides. Also this layer would have to be sliced into tiles and encoded into RGB format, so integrating it into Streets GL may take a while.

Edit: It seems like there is a sliced version of this layer: https://www.arcgis.com/home/item.html?id=7029fb60158543ad845c7e1527af11e4

I've changed the elevation tileset from Mapbox Terrain-RGB v1 to Esri (ArcGIS) Terrain 3D. The quality is much better, so I think this is going to resolve most issues with bad elevation data.
