builder.resid.resid.Filter8580

public class Filter8580
extends Filter

Filter for 8580 chip based on a simple linear approximation of the FC control.

This is like the original reSID filter except the phase of BP output has been inverted. I saw samplings on the internet that indicated it would genuinely happen like this.
