It is practical to de-noise only on luma while keeping chroma unchanged.

However, libavfilter/vf_owdenoise.c always do the Wavelet transform/retransform on all 3 channels without check whether chroma_strength is 0.

Thus I make this patch. De-noise on Y only for yuv420 is now 1.5 times faster.

The intent here is similar to colormatrix, but it's LGPLv2.1-or-later
(instead of GPLv2.0) and supports gamma/chromaticity correction.
