I previously changed it to use the absolute inter-prediction mode values instead of the ones relative to NearestMv. That caused the probability adaption to take invalid indices from the counts and broke certain videos. Now it will just convert to the PredictionMode enum when returning from parse_inter_mode, which allows us to still use it the same as before.
