Module draft18 

MoQT wire codec for draft-18 (latest). MoQT wire codec for draft-18.

Key changes from draft-17:

• Required Request ID Delta field removed from every request message
• SUBSCRIBE_NAMESPACE renumbered to 0x50 and subscribe_options removed; FORWARD parameter moves to the new SUBSCRIBE_TRACKS (0x51) message
• PUBLISH_OK collapsed into REQUEST_OK (0x07); REQUEST_OK gains a trailing Track Properties block
• GOAWAY gains an optional request_id (present only on the control stream); may also be sent on individual request streams
• REQUEST_ERROR adds REDIRECT (0x34) with a Redirect structure and UNSUPPORTED_EXTENSION (0x33)
• DELIVERY_TIMEOUT renamed to OBJECT_DELIVERY_TIMEOUT (still type 0x02); new SUBGROUP_DELIVERY_TIMEOUT (0x06) and FILL_TIMEOUT (0x0A) parameters
• New TRACK_NAMESPACE_PREFIX parameter (0x34) for REQUEST_UPDATE
• PUBLISH_DONE status codes 0x5/0x6 swapped: 0x5 = TOO_FAR_BEHIND, 0x6 = EXPIRED
• SUBGROUP_HEADER gains FIRST_OBJECT bit (0x40); type ranges expand to 0x10..0x1F, 0x30..0x3F, 0x50..0x5F, 0x70..0x7F
• FETCH stream objects use delta-encoded Group ID and Object ID
