Add Paper Link to Repo #162
Description
Is your feature request related to a problem? Please describe.
I can't find a link to the paper on the GitHub repo page. I am creating this as a separate issue from #60, although it is mentioned there as well.
Describe the solution you'd like
I'd like to see it set up like CMakePPLang where there is a "Cite this repository" button under "About" and the README has a badge displaying for the paper.
Describe alternatives you've considered
We could just put a section in the README linking the paper and maybe providing a BibTex citation block.
