Verified that this creates valid input for the Apple Prores Encoder which
is great.

A side-note: In our transcoding set-up I just quickly compared the
performance of that conversion (in the test case from yuv420p -> AYUV16LE)
is still slower than our previous setup with conversion yuv420p ->
YUVA444P10LE using swscale and then doing the YUVA444P10LE -> AYUV16LE
conversion in Java but I guess that is because there is no asm for this.
