Consider citing relevant paper(s) in DESCRIPTION

[mdingemanse]

          Given that we are citing these papers here, we should consider putting them in the Description, too. CRAN has specific requirements for citations in the description though, so let's keep that in mind:

• Relevant citations should be included in the description. These should be in author-year style, preferably followed by an identifier such as DOI, arXiv id, or ISBN for published materials.
• DOIs should be enclosed in angle brackets, and formatted as doi:10.prefix/suffix. Example: Sugihara (1994) doi:10.1098/rsta.1994.0106.

I think Liesenfeld & Dingemanse 2022 LREC would be a relevant cite, but don't want to suggest it is the go-to cite for talkr.
