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.

Call a row function for each row, based on ARGBToI400 code.
But implement row functions as 2 step conversion. Adds the
row functions:
RAWToYJ, RGBToYJ, SSSE3 and AVX2 versions, and Any versions.
The smaller row buffer is more cache friendly on large images.
The max cache size can be configured, and is currently:
// Maximum temporary width for wrappers to process at a time, in pixels.
And the row buffer is
SIMD_ALIGNED(uint8_t row[MAXTWIDTH * 4]);
So 8192 bytes are used for the row buffer, leaving the rest for source
and destination buffers.
