This PR introduces

  1. Depth sort on GPU, using paralell bitonic sort
  2. Fixes vertical mouse controls
  3. Retargets from es5 to es6 (since webGPU only works on recent browsers anyway)
  4. Introduces an FPS counter
  5. Renames the typescript package to gaussian-splatting-web and properly sets its version to 0.0.2
