Similar to VP8, to adjust the positive and negative data and prevent small
probability overflow during calculations.

Initially, they used the same code, but after testing hundreds of times,
there were always a few failures...

Because the data in the table is different, when regular, sharp, and smooth
use the same code, there will always be a small amount of overflow.
Different signed and unsigned calculations are needed.

Got it, I will try to update.
