Description
A way to capture the suggestion given in [discourse](https://discourse.julialang.org/t/optimal-power-of-n-for-fftw/85232/9).
[stevengj](https://discourse.julialang.org/u/stevengj)
An FFTW.nextfftlen(n) function would be reasonable, along with FFTW.nextrfftlen(n) for real-input FFTs (which favor even lengths). But I think this would be in addition to an N-smooth nextsmooth function in Primes.jl.
