Description: Computes discrete Fourier transforms (complex,
        real-to-complex and complex-to-real) and discrete cosine and
        sine transforms of types one to four over any axes of an array,
        with the fast Fourier transform (FFT) code of 'ducc0'
        (<https://github.com/mreineck/ducc>) bundled in the
        BSD-licensed subset that 'SciPy' uses. Transforms of any length
        run in O(n log n) time, real input uses true real transforms,
        and several threads can share one transform.
