Conformance tests

Maybe there is something useful here https://www.certification.openid.net/

Seems actually be OIDC specific. But maybe there is something we could use.

I am not really sure what this is, is it a demo?

Oh nvm I see the info about this here https://openid.net/certification/about-conformance-suite/

If we can get this running locally somehow in a reproducible way we can integrate this into our CI and run this, for example, on release-* branches.

I'm closing this issue.

Based on #79 I conclude that we can't test this directly on the library it self. We also have an open issue that covers security (#65).
