Johannes Günther 6c01601125 Sampling improvements 
- changed low-discrepancy sampler from Sobol with Cranley-Patterson
  rotation to shuffled and fast Owen-scrambled Sobol (Burley 2020)
- optimized implementation (support maximum of 64k samples)
- keep plain implementation for debugging
- enable screen-space blue noise via parameter `targetFrames` at the
  framebuffer (because the total number of samplers needs to be known in
  advance)
- splitting for NEE with >1 light samples
