Turn the AGC coeffs inside out: array of structs instead of a struct of little arrays.
In C++ use a vector<AGC_coeffs> for this; each of 4 stages has an entry; many fewer places
need to do indexing by stage, and this removes the temptation to use little eigen arrays
for the 4 stages.
Also latest version of experimental log-lag SAI hacks.
