Support marker icons in Geospatial View node

[koettert]

As a user I want to use build-in and custom icons when representing points on a map.

Partially related to having custom icons appear on the map. Would it be possible to consider the possibility of the geospatial view node respecting the row colour as defined by the colour node? It appears that the OSM map view visualizer does adhere to these criteria, whereas the geospatial view node currently does not. Many thanks!
