if 0 is encountered in the LUT then decompress() will continue to output 0 bytes but never read more data.

None of the valid prosumer files tested cause a 0 to be read, so it is likely
not a intended feature.

It seems what this function does is a vertical prediction filter, thus
the new name should improve understanding.
rename the related table_b too
