Frontend/visualiser (#24)
* refactor to src folder * add working voronoi js file with types * some spring cleaning * update voronoi-core.d.ts to include inner class exports * make voronoi go really fast * do the voronoi dance * better handle outliers in voronoi * make renderer use multiple layers * resize voronoi with resize + squash all in one buffer * actually wait for shader factories to be created + cleanup * show more info with FPS Counter * POWER UP
