repeat y for yuy2 so that unittests that check the 2nd y on odd widths will match the C and SIMD.  The C code duplicates the last Y.

 Enter a description of the change.

use SIMD for I420ToARGB odd widths in a temporary buffer instead of using C for remainder.  Currently the C code does not exactly match the SIMD code, so an odd width produces different pixels than an even width, causing a subtle artifact.  By using SIMD consistently, there is no difference in even and odd widths.  Also the SIMD performance is faster, so even with overhead of memcpy, performance improves.

Box filter for YUV use rows with accumulation buffer for better memory behavior.  The old code would do columns accumulated into registers, and then store the result once.  This was slow from a memory point of view.  The new code does a row of source at a time, updating an accumulation buffer every row.  The accumulation buffer is small, and should fit cache.  Before each accumulation of N rows, the buffer needs to be reset to zero.  If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.

Change Sobel to use JPeg Luma calculation instead of extracting G channel.  Using luma produces a better sobel that respects all 3 channels of RGB.  Historically the G channel was used to improve performance, and because the luma of I420 is a constrained range, hurting quality.  Using the JPeg variation of YUV, the luma is more accurate, including cross platform, better optimized for AVX2 and odd widths, and full range.
