For non-power of two sizes, use the generalized Cooley–Tukey algorithm, to recursively factorize the FFT (aka mixed-radix): https://en.wikipedia.org/wiki/Cooley%E2%80%93Tukey_FFT_algorithm#Variations
For stages of this decomposition involving large prime factors, use Rader's algorithm to zero pad the FFT to a power of two: https://en.wikipedia.org/wiki/Rader%27s_FFT_algorithm
It's possible to do a mixed-radix bit reversal, but we can set that aside for a future optimization.
