Integrate some sort of denoising algorithm #8

Currently the application is struggling a lot keeping up. A very good optimization would be some sort of fast denoiser to allow for fewer rays. The raytracing shader should also use a blue noise texture to skip certain pixels to save on some computation (and make it easier to denoise)
