Support for Co-signing / Counter-signing / Multi-signature #99

Conformity certificates often carry more than one signature. I would like to see this group suggest a common data model to support this.

Off the top of my head, I could imagine something like a CountersignCredential which either includes the entire already-signed credential, and/or references.

Proof chain and proof set are supported in vcdi: https://www.w3.org/TR/vc-data-integrity/#proof-chains

I also recommend the parallel signatures feature of the data integrity securing mechanism which addresses just that.
