ecosystem: merge signal and image processing?

[mdeff]

I think image processing should be seen as a subset of signal processing (wikipedia agrees). That separation is probably due to signal processing being historically 1D, while we now have nD Euclidean SP and non-Euclidean SP on manifolds/graphs/homogeneous spaces/groups/etc. thanks to abstract harmonic analysis and the underlying group and representation theory. I'll make a PR if people agree.

I'd prefer to keep these separate. xref gh-313 for full update on categories.

This is fair from a mathematical point of view, but from a Python users and general scientist background point of view, those are things no one really wants to know about. As you say, the fields are historically separate - and they still are mostly separate for the average user. Plus I want to limit the maintenance work here (e.g., we have new icons for both of these in gh-369 now).

Yeah, it's probably better for categories to follow mainstream usage. Let's hope they merge one day. :)
