Fixes ticket #128.
The SVQ1 interframe mean VLC symbols -128 and 128 are incorrectly swapped
in our SVQ1 implementation, resulting in visible artifacts for some videos.
This patch unswaps the order of these two symbols.

compressed_ten_bit_format has been deprecated upstream and has no effect
and can be removed. Plus, technically it was never used in the first place
since it would require the app (ffmpeg) to set it and do additional
processing of the input frames.

Yes, the space is limited and we could bikeshed until christmas about

Here's an attempt with an 'av' prefix, 'ft' (frame thread) changed to
