Support Color Manager colorizations of geospatial objects for Geospatial View

[sturmkev]

For all native KNIME views, I can use the Color Manager node to assign colors (numerical: color gradient; categorical: distinct colors) to a column.

It would be desirable, if I can use the Color Manager to assign colors to a dedicated column (numerical or categorical - not the geospatial column) and those colors will be picked up by the Geospatial View later on.
As we are currently using Matplotlib as a library to assign color settings directly within the Geospatial View node, the colors, originating from the Color Manager, need to be somehow compliant.

It should be clear which column should be used to colorize the geospatial objects within the Geospatial View, since a KNIME table can hold colorizations for more than one column.
