Struct std::IirFilter32

#include <std/dsp/filter.h> source

struct IirFilter32 {
    const &float b;
    unsigned long numB;
    const &float a;
    unsigned long numA;
    &float xHistory;
    &float yHistory;
    unsigned long xPos;
    unsigned long yPos;
}

Single-precision IIR, same contract as IirFilter. Float rounding grows with the order; cascade Biquad32 sections for anything steep.
