adding Citation files to cookiecutter-data-science template

[kjgarza]

CITATION.cff files are plain text files with human- and machine-readable citation information for software (and datasets). Code developers can include them in their repositories to let others know how to correctly cite their software.

It is very easy to correctly cite a paper: all the necessary information (metadata) can be found on the title page or the article website. Software and datasets have no title page, the relevant information is often less obvious.

Hi @pjbull, I was just wondering if someone had a chance to discuss this PR? thanks

[pjbull]

@kjgarza I think we'd consider this during the transition to v2, but to me it doesn't seem super likely given that only a small fraction of data science projects will have an associated citation. Could you file an issue instead and link to your branch in your fork?

Great work @kjgarza.

Actually, some would argue that including the CFF file as part of data science or research templates is fundamental as it might nudge users into the desired behaviour. Shout-out to @hainesr @danielskatz @npch, maybe they can provide more context here.
