Auto-detect zotero csvs?

[LukasWallrich]

Currently, users need to notice that we have a separate option for Zotero csvs. Should we instead check if a csv has the Zotero-specific fields (e.g., "Manual.Tags" and "Publication.Year") and then just rename accordingly. I don't think that would ever go wrong, and the gsub on pages would also do no harm to other csvs?

          @tayates note that ASySD directly support Zotero csv s if you import them with method = "zotero_csv"
