Publish links

[blue442]

Addressing #187 by adding the functionality where foundry.publish_dataset() can take links in the form of a keyword argument. The arguments associated with the links keyword are of the following form:
{"type":str, "doi":str, "url":str, "description":str, "bibtex":str}
following the convention laid out in the MDF data schemas, and can be included as a single argument or a list of arguments.

Some light validation is performed to ensure that the keys in each of the link conform to the options described in the MDF schema (but are all optional); violation results in a ValueError being thrown.

After validation the links are passed to the add_links() function from the MDF connect client.

Tests were included in test_foundry.py to test the successful addition of links as well as ensuring the validation process works successfully.

NOTE: This branch was based off of the reviving_load branch which is yet to be merged to main, and therefore appears to contain more changes than intended.

Looks great! All that's left to finalize this is updates in the GitBook documentation and in the example notebooks (under /examples). Let me know if you're having trouble with the GitBook documentation -- you can open an Edit Request which is like a PR there

the publishing example addition looks mostly very good, thank you steve! could you just add what the other options are in the comment above the example links? And in the documentation, it would be good to define the different options (eg "other_paper", etc) more thoroughly.

Also, can you clear the output of this cell and repush the publish example notebook?
