Allow ORCID links for people dataset authors

[PGijsbers]

It would be nice to provide a standardized way to provide ORCIDs for fields that mention people, so that they can be referred to in a non-ambiguous way.

We could add some syntax to the authors field to allow people to specify this extra information, e.g.: Gijsbers, Pieter (ORCID:0000-0001-7346-8075), and the website could render the name as a hyperlink to the orcid.org page. The dataset upload endpoints would need to accommodate a user-friendly way to add this information, without the user needing to have knowledge of how to format the field.

Alternatively, we could add additional fields. Perhaps in our database we add a Person table what gives each person a unique identifier and stores the name and ORCID (or multiple tables if we want to support other references). This also makes it easier to group datasets by author. However, this does introduce additional bookkeeping.

Personally, the first method seems OK to me, as we can in a non-destructive manner still progress to other schemes later. WDYT?
