Use payload interface to unpack group/IANA from message

Directly calling unpack from the Request interface will attempt to
unpack the whole message, resulting in a 0xC7 response if the whole
message was not unpacked. Since at this point in the execution, the
point is to only extract the group ID or the IANA, the lower-level
Payload unpack interface must be used. This allows for partial unpacks
and only returns error if there are not enough bytes to unpack.
