add Zenodo DOI for citations?

[davedgd]

@singmann: Thank you for providing this convenient package (which I found via an old R-sig-ME discussion you had with Guillaume)!

Regarding this package, I imagine you're not planning on releasing this on CRAN any time soon given it hasn't been updated in a while, but I was wondering if you'd consider creating a citable DOI via Zenodo so we can reference it more easily in research?

Thanks again Henrik!

Thanks for the idea and glad to know this package is of use to you. I have tried to create a zenodo doi. It should be here: https://zenodo.org/record/4697305

I have also added it to the README. Please let me know if this is enough.
