`6` is the decimal for 0110 where those middle bits represent the chroma
planes; the right represents luma, and the MSB represents alpha i.e. AVUY

I'm not sure this will do job, though.If there's any legal YUV triplet
which maps to out-of-bounds RGB this filter won't sanitize it.

The crude way is to roundtrip via RGB using scale.
