small technical error at the start of the readme

[Pomax]

The readme opens with "QuiFFT is a Fourier transform (FFT) library for digital audio files" but those two things are not the same. The Fourier Transform is just "FT" (with the discrete fourier transform being "DFT"). The acronym "FFT" is specifically and only for the "Fast Fourier Transform", a DFT that only works when the input data is constrained to powers-of-two windows, but works stupidly well with that constraint in place.

So it would be better to change that to either "QuiFFT is a Fourier transform (FT) library for digital audio files" with the wikipedia link that you're currently using, or "QuiFFT is a Fast Fourier transform (FFT) library for digital audio files" but then point to https://en.wikipedia.org/wiki/Fast_Fourier_transform instead.
