This CL makes possible to choose the level estimation for the adaptive digital GC of AGC2. The options are RMS (default and currently used estimator) and peak-based (already computed, but not used). Besides adding the new AGC2 config param for the level estimator, this CL also refactors the config class by making it more structured.
