remove for loop from point splatting #12

For point splatting with fuzzy depth test, we first need to compute the closest distance: This part does not need to be differentiable

[x] Zbuffer without a for loop
[x] Add back z<0 and culling tests-

Move on to the rendering part with the fuzzy depth test and aggregate features. This part needs to be differentiable.

[x] aggregate colors ...

The key operator here is scatter_reduce_ scatterreduce
