Re: [webauthn] Adding CDDL to txAuthSimple

@equalsJeffH 

>if using maps, is not the key "txAuthSimpleArg" also part of the CBOR-encoded object? If so, do we really need to transport those bytes down the stack (do they add any value)?

As per https://w3c.github.io/webauthn/#sctn-authenticator-extension-processing, "The CBOR authenticator extension input value of each processed authenticator extension is included in the extensions data part of the authenticator request. **_This part is a CBOR map_**, with CBOR extension identifier values as keys, and the CBOR authenticator extension input value of each extension as the value."

I interpreted the above to mean that the authenticator extension input is always presented to the authenticator as a CBOR map.  I agree that this may be inefficient in the case of txAuthSimple, but I don't know how else to interpret the above requirement.
