[saag] Minor SFrame update: IANA and AES-256-CTR-HMAC

Hi SAAG folks,

FYI, Emad, Aron, and I just published a new draft related to SFrame.

https://datatracker.ietf.org/doc/draft-barnes-sframe-iana-256/

It does two things:

1. Update the SFrame Cipher Suites registry to be more descriptive
2. Register code points for the SFrame AES-CTR-HMAC construction using
AES-256 and SHA-512

Since the SFrame WG is closed and these are both minor changes, Paul
graciously has offered to AD-sponsor the draft.  So process action is
needed from SAAG or any working group, but feedback would be welcome.

Best,
--Richard

Abstract:

   This document addresses two omissions in the Secure Frames (SFrame)
   protocol specification.  First, the definition of the IANA registry
   for SFrame ciphersuites omits several important fields.  This
   document requests that IANA add those fields and defines the contents
   of those fields for current entries.  Second, the AEAD construction
   based on AES-CTR and HMAC is defined only for the 128-bit security
   level.  This document registers parallel constructions at the 256-bit
   security level.
