Module draft19 

MoQT wire codec for draft-19 (latest). MoQT wire codec for draft-19.

Key changes from draft-18:

• Request ID field removed from GOAWAY entirely; control-stream and request-stream GOAWAY now share one format
• New Range Filter parameters (length-prefixed): SUBGROUP_FILTER (0x25), OBJECTID_FILTER (0x26), PRIORITY_FILTER (0x27), OBJECT_PROPERTY_FILTER (0x28) and TRACK_PROPERTY_FILTER (0x29)
• New Setup Options MAX_FILTER_RANGES (0x06) and MAX_REQUEST_UPDATES (0x08) (even KVP types, varint values)
• GROUP_ORDER (0x22) moves from PUBLISH_OK to SUBSCRIBE_TRACKS
• PUBLISH_BLOCKED renamed to PUBLISH_SKIPPED (still type 0x0F, wire identical)
• SUBSCRIPTION_FILTER renamed to LOCATION_FILTER (still parameter 0x21)
• REQUEST_ERROR adds CONFLICTING_FILTERS (0x35) and INVALID_FILTER (0x36); DUPLICATE_SUBSCRIPTION (0x19) removed as multiple concurrent subscriptions per Track are now allowed
• Session error TOO_MANY_REQUEST_UPDATES (0x1B) added
• Data stream headers (subgroup, datagram, fetch) are byte-for-byte identical to draft-18
