Uniform Weighted.Sample Light Source for direct lighting, 4spp spents 289secs on Apple M4. Much Better!

Cosine Weighted.Sample Light Source for direct lighting, 4spp spents 347 secs on Apple M4. Much Better! By the way, an interesting but confusing problem is, the same program spents 1721 secs on Intel Core Ultra 9 285H and Windows.

Cosine Weighted. Using Shadow Ray to sample direct lighting,16spp spents 30mins on Apple M4, quite noisy.
