🛂 ORCiD authenticator

Prototype authentication to ORCID:
https://info.orcid.org/documentation/api-tutorials/api-tutorial-get-and-authenticated-orcid-id/

NOTE: you might have to create a personal 0Auth account for testing purposes, but we'll prolly have to use an organizational 0Auth 2.0 client ID.
In any case, DON'T commit any credentials.
