#2475: support yuv422p10le in lut filter

Summary of the bug:
I would like to use the lut filter with 10 bit video (encoded as v210),
but it only supports 8 bit yuv pixel formats. In the example below the
input is 10 bit, the filter's output is 8 bit, and then the output has
zero-filled least significant bits (9 and 10). Could the lut filter
support >8 bit formats? Thanks.
How to reproduce:
{{{
ffmpeg -i 10-bit_test.mov -vf lutyuv=u=128:v=128 -c:v v210 -c:a copy -y 10
