These functions convert between planar and interleaved ARGB,
optionally fill 255 to alpha / discard alpha.
This can help handle YUV(A) with Identity matrix, which is
basically planar ARGB.

M420 is a row biplanar variation of NV12 supported on Microsoft webcams.
The code was hardcoded to bt.601 and should be jpeg, but the format is
very old and rare. Is a variation on NV12, so if someone needs it, it
can be re-implemented easily.
