Use MapLibre for Map Visualization (#300)

* switching to MapLibre (see more at https://github.com/usds/justice40-tool/issues/299)
* Removing traces of OpenLayers
* Review comments - removing unused properties, component
This is a pre-requisite for addressing issue #280 and other similar control-related tickets
