Minimal stereo feedback delay network.
This first version defaults to one delay line for the left channel and one delay line for the right channel, but the storage is parameterized by an equal number of delay lines per side:
s[n] = delayed x[n] x[n] = u[n] + feedback * A * s[n] y[n] = dry * u[n] + wet * s[n]
where A is currently a 2x2 stereo rotation over the per-channel line mix. Later versions can expand A into the full per-line block matrix.
