optionally (use_lpc=2) support Cholesky factorization for finding the lpc coeficients

this will find the coefficients which minimize the sum of the squared errors,
levinson-durbin recursion OTOH is only strictly correct if the autocorrelation matrix is a
toeplitz matrix which it is only if the blocksize is infinite, this is also why applying
a window (like the welch winodw we currently use) improves the lpc coefficients generated
by levinson-durbin recursion ...
optionally (use_lpc>2) support iterative linear least abs() solver using cholesky
factorization with adjusted weights in each iteration
compression gain for both is small, and multiple passes are of course dead slow
