Stop decoding unused Community and Raw fields of RIS messages (closes #9)
check / check (push) Failing after 1s
Details

Browse Source 
Community and Raw are decoded from every live message and read by no
handler; Raw is the hex of the whole BGP message. Each parsed message
sits in up to four handler queues, so retaining them is a large share of
queue memory. Tagging both json:"-" keeps them out of the decoded
message while the fields handlers use still decode. A decode test over
docs/message-examples.json confirms both stay empty and the used fields
(Path, Announcements) still populate.
