Add "description" to list of fields that MAY be included in stream creation
In section 7.1.1.1, we say that the stream creation request MAY include any Receiver-supplied fields, and then we list events_requested and delivery. We should either include description as well, or remove the list and let implementers discover which fields are Receiver-supplied above in section 7.1.1 (the latter option being more future-proof if we add any other Receiver-supplied fields in later versions).
Seems reasonable. You haven't marked this for v3, so would you like this to be addressed right now, or after v3?
It's not essential. We can wait until after v3, since it is just a clarity edit.
Pull this out of #195 into its own PR since it is a normative change
