feat: mso mdoc handling

[TimoGlastra]

allows handling of mdoc presentations using integration with pex.

What it does:

• parse/evluate vp token / definitions with mdoc (and other formats combined, tests for this in pex repo)
• select credentials for pd with mdoc (and other formats combined, tests for this in pex repo)

What it doesn't do:

• extract and verify the nonce from the mdoc presentation. We can enable this when the device respnose parsing is mixed in mdl lib. However as the nonce is part of verifying the session transcript it's not really an issue
• allow creating a VP with mdoc. In the test i bypass this. We need the device response stuff for this and some better typing. It's mostly focused on the verifier role for now

Needs Sphereon-Opensource/PEX#184 to be released and add for tests to succeed.
