Adding a DOI

[maia-sh]

Thank you for this great package! I have a dataset which I plan to release in iterative versions and would like to mint a DOI for each version (e.g., via Zenodo). I would also like to include the DOI, e.g., as an "identifier" in the metadata via "biblio.csv". I haven't been able to find any guidance in the package docs or other issues. Is there a workflow for this, or more generally working with {dataspice} and DOIs?
