“amr” Values specification addressing IETF last call comments

Draft -05 of the Authentication Method Reference Values specification addresses the IETF last call comments received. Changes were:

• Specified characters allowed in “amr” values, reusing the IANA Considerations language on this topic from RFC 7638.
• Added several individuals to the acknowledgements.

Thanks to Linda Dunbar, Catherine Meadows, and Paul Kyzivat for their reviews.
