This CL reduces the complexity and heap usage of the adaptive filter in AEC3 by avoiding to compute these for the shadow filter. In particular it -Moves to compute the ERL, frequency response and impulse response on an on-demand basis. -Stores the ERL, frequency response and impulse response outside of the adaptive filter. All the changes have been tested for bitexactness on a sizeable amount of recordings.
