Validate VC in JWT format for matching sub and credentialSubject.id

[stevenvegt]

Credentials in JWT format has 2 ways of defining a subject:

{
  "sub": "did:web:123",
  "vc": {
    "credentialSubject": {
      "id":"did:web:123"
    }
}

Parsing should warn or error if these fields are not equal?
