Experiment to adapt for net AQ offset. In Aq mode 1 the segment and AQ delta for each block is based on spatial variance. There may be a net imbalance between blocks that have lower Q than the baseline value and those that have higher Q. This patch monitors that imbalance and extends the allowed baseline Q range for the frame to accommodate adjustment of that baseline value to compensate.
