AEC3: Changes to how the reverberation decay is applied.

In this work we introduce some changes on how the reverberation model for AEC3 is applied. Currently, the exponential modelling of the tails is applied over the linear echo estimates. That might result  in an overestimation of the reverberation tails under certain conditions. In this work, the reverberation model is instead applied over an estimate of the energies at the tails of the linear estimate.

Additionally, the stationary estimator is changed so it does not disable the aec immediately after a burst of activity.
