supported signed URLs

[pdurbin]

Signed URLs as a more secure alternative to API tokens will be supported in a future version of Dataverse, probably 5.13 since the pull request has already been merged:

• GDCC/7715 Signed Urls for external tools IQSS/dataverse#9001

For now you can read the docs here: http://preview.guides.gdcc.io/en/develop/api/external-tools.html#authorization-options

@bappun just asked about it and I'd love to see this too. Thanks! 😄
