libkissfft-float131 131.1.0-1 (armhf binary) in ubuntu jammy

 There are many great fft libraries already around. Kiss FFT is not trying to be
 better than any of them. It only attempts to be a reasonably efficient,
 moderately useful FFT that can use fixed or floating data types and can be
 incorporated into someone's C program in a few minutes with trivial licensing.
