Eventual move to the `linfa` crate? about asterusk HOT 1 OPEN

Just took a look at linfa! I have absolutely no issues with moving the work/continuing future work into linfa. I'm happy to help build convolution tooling in the most effective way.

In moving to linfa, I'd like to suggest we build up from an even lower level, if possible. In some contexts it would be quicker to carry out convolution in the frequency domain (although its definitely not a one size fits all, as it tends to work well with larger convolutions). We could offer convolution in both flavors (fft method or traditional matrix multiplications as I believe you have already implemented) for more variety.

I'd like to get work done in generalizing the fft for n domains as a first step. There is currently a crate called ofuton that does this, but its no longer maintained. This is pretty much what I'd like to have a base before solving the convolution problem. Do you think this is something appropriate for the linfa crate? Would it accidentally be against the spirit of the crate?

Otherwise, I think there's benefit in centralizing our efforts!
