denoiser property
Optional temporal denoiser. When non-null, each inter frame's
luma plane is pre-filtered against _prevLast (low-motion MBs are
blended toward the reference) before motion search and residual
encode. Reduces bitrate on noisy webcam content without any
decoder change. Keyframes are never denoised (no reference yet).
