SD-JWT: Add option for non-selectively disclosable claims (issuer)

[sandrask]

The Issuer may also make certain claims or sub-claims non-selectively disclosable. Add option for specifying non-selectively disclosable claims to issuer.

For example if you don't want id and degree type to be selectively disclosable then you can pass non-selectively disclosable claims option that is configured with following array {"id", "degree.type"}

{ "degree": { "degree": "MIT", "type": "BachelorDegree", "id": "some-id" }, "name": "Jayden Doe", "id": "did:example:ebfeb1f712ebc6f1c276e12ec21", "spouse": "did:example:c276e12ec21ebfeb1f712ebc6f1" }

would result in:
{ "_sd": [ "4zh-KxicMAPtR6-O1Q1C5hJdqYMl6RcnvOXOod7EEVU", "rbeadqlWMg3eR9GGDGrxPOYhoqZ770tkIRkCWaC6Ve8" ], "_sd_alg": "sha-256", "degree": { "_sd": [ "N1JdJNBsy_uQ79XG8yzEaXnm0sHX5b5Ad6MM2nU7iqo", "CKURc0Nqvx4DkSpvW3WAt0idTZKNJo7SshkmA1gBAQI" ], "type": "BachelorDegree" }, "id": "did:example:ebfeb1f712ebc6f1c276e12ec21", }
