Update supercluster for improved performance

[IslamRustamov]

Official supercluster github repo says that 8.0.0 has an improved performance for clustering and reduced memory footprint. (https://github.com/mapbox/supercluster/releases/tag/v8.0.0) It also has an updated version of kdbush which doesn't throw an error if there are no markers on the map.

I wouldn't hold your breath getting this/anything merged. If you use yarn you can add this to your package.json and add it yourself

  "resolutions": {
    "supercluster": "^8.0.0"
  },
