Description

Currently Facet Heatmap(Geographical facets) do not support any other subjects other than WKT or '[ ]'. This seems to be caused since FacetHeatmap.Parser#parse uses SpatialUtils#parseGeomSolrException, which in turn uses a deprecated JTS method (SpatialContext#readShapeFromWkt) to parse the string input.
The newer method of parsing a String to a Shape object should be used, makes the code a lot cleaner and should support more formats (including GeoJSON).
