multidimensional nufft? #144

Hi,
I noticed that 2D nufft’s of types I-I and II-II are mentioned in the discourse in 2017.
As I looked at the code, it seems that the interface of nuffts only accepts AbstractVector as input.
The question is does FastTransforms.jl support multidimensional FFT?

I think it would take a skilled programmer just a couple weeks to get the Townsend--Ruiz-Antolín method to work for one, two, and three dimensional NUFFTs. See the related issue #102. Note that there are also other repositories that might work for you: https://github.com/tknopp/NFFT.jl, https://github.com/ludvigak/FINUFFT.jl
