Update citations

[BradleySappington]

Establishing a CITATIONS.cff file to be in line with citation best practices. If anyone is going to use the software for data, or for a reference in a repository or paper, then the credits for this software will be maintained in the CFF file (which gets pushed into the zenodo doi through our repository). So this will be used for giving credits for authors (in the exact versioning) for any papers/software where WebbPSF will be used.

I added @Skyhawk172 and @mperrin myself. Couldn't find other orchids from contributors in our slack channel who are affiliated with Space Telescope Science Institute

Let me ping here some other past contributors to webbpsf, in case any of them would like to also be included in the author list as recorded in the CITATIONS.cff file. If any of you excellent folks would like to also be included in that, can you please provide us here with your ORCID ID, etc?

Thanks for the heads-up @mperrin ! My current employment details can be found here: https://orcid.org/0000-0003-1905-9443

I think it would be a good idea to preserve the references to cite-able entities like SPIE proceedings (that this pull request removes) somewhere, either in the docs or the README. I have also seen a .bib file in the repo root used as a de-facto standard in the machine learning world, which I like because I already use BibTeX. (That could also contain the ASCL reference as a @misc.)

@mperrin @obi-wan76 I think we are good to review/merge this is, we can update outliers in future PRs.
