PIMS-1675 Replacing MarkerCluster with Supercluster

[dbarkowsky]

🎯 Summary

PIMS-1675

Changes

• Swap out previous cluster package with a simpler but faster one
• Rework spiderfier and point clusterer logic from old PIMS to work in new PIMS.
• Fix errors with MapPropertyDetails
• Adjust endpoint for geojson data

Testing

• Navigate to /dev endpoint
• Use map, opening and closing clusters, etc.

This approach didn't come with all the bells and whistles as the last package, but I think it scales better. I have about 25000 properties on my map, and there's no slow down, compared with the last package which had major loading times.

In the future, it would be good to tweak some of the behaviours of the clustering. Maybe we could find a way to implement smooth movement as well.
