Convenience functions that create an Fft object, run the FFT or inverse
FFT and return the result. Useful for one-off FFTs.
Note: In addition to convenience, these functions are slightly more
efficient than manually creating an Fft object for a single use,
as the Fft object is deterministically destroyed before these
functions return.
