[Feature Request] Discrete Hankel Transform

[steven-murray]

Is your feature request related to a problem? Please describe.

A lot of science users really want to do a HT on discrete data, which is possible with the current algorithm, but it is not tuned for that case.

It might be nice to add the discrete HT in.

Do you have any literature recommendations for the discrete Hankel transform?

I had started with this: https://www.intechopen.com/books/fourier-transforms-century-of-digitalization-and-increasing-expectations/the-discrete-hankel-transform

I've also started a branch for this a while back but haven't had time to complete it. There's a fairly long discussion on getting it work on an issue in another repo, but I can't remember where! If I find it I'll link it here.

I've pushed up that branch now -- there's a notebook in the devel directory in that branch that may or may not be useful :-)
