[Cbor] New EAT draft using CDDL for information model

[Laurence Lundblade <[e-mail]>]

This separates the information model from the data model. The information model is described using CDDL. I used a CDDL group for each claim. Hopefully this is a good way to do it. In later sections the extra details needed for CBOR and JSON syntax are given. I’m not so much after conversion between them. What is important that they both be able to express the same claims so you don’t have a situation where “you have to use CBOR if you want claim XXX” (or vice versa).

> Abstract:
>   An Entity Attestation Token (EAT) provides a signed (attested) set of
>   claims that describe state and characteristics of an entity,
>   typically a device like a phone or an IoT device.  These claims are
>   used by a relying party to determine how much it wishes to trust the
>   entity.
> 
>   An EAT is either a CWT or JWT with some attestation-oriented claims.
>   To a large degree, all this document does is extend CWT and JWT.
