Add relaxed max partition prediciton mode

Introduce a new metric to determine the max partition prediction
using NN.
The new metric performs on cumulative probabilities. Starting from
the largest size, the prediction is where the cumulative prob
exceeds 0.2.
This metric often produces a relaxed(bigger) max part prediction
compared to just picking the size with the highest score.
This mode is enabled on videos >= 480p but < 720p.

midres: speed up 5.7%, BDRate 0.052%
