Get all Finnish Social Science Data Archive (FSD / Aila Data Service)
links: real hyperlinks from the paper's own url table (the catalogue
page, a 10.60686 DOI, or a urn.fi URN), plus a body-text fallback for a

hyperlink. Same two-tier approach github_links() uses for GitHub.
Examples
paper <- demopaper()
fsd_links(paper)
