Create CITATION.cff

[abhro]

Addresses #571. This citation file does pin to a release, so it's probably a good idea to add a step like "Update the CITATION.cff file" to a release checklist. In either case, it works as a basic citation skeleton before something like JOSS or Zenodo is finalized.

I happened to pick the contributors from the thread of #571, and seeing who was active in the contributors section in the main page (the Insights>Contributors graph is taking a long time to load.) So I'm not sure if I missed out on any contributors. I think @SimonDanisch since he's also a big contributor of Makie? But I don't know who's involved with which parts of the project, so I'm being fairly conservative for the moment. Would love the input of @piever on this.

Hello and thank you for this! There is some a JOSS paper in the works (cc @jkrumbiegel), but in the meantime a citation file might be helpful.

Not sure what are the guidelines here (maybe Julius has a clearer view), but in terms of important contributors, I think it makes sense to include Simon and @greimel (Fabian Greimel), who was very active in the project already in the early stages (faceting and legend were the most substantial contributions off the top of my head). The contributor graph doesn't load for me either for some reason, but they both contributed substantially both conceptually with design discussions and practically with code.

I have opened a JOSS proposal now, although it's not yet publicly visible. We can use that once it's finished.

So is the current form of the PR good to merge?

I'd just leave it open until there's an actual paper to cite
