Ws rfq feed data v1

Name `Lite`	Type	Required `Default`	Description
stream `s`	string	True	Stream name
selector `s1`	string	True	Primary selector
sequence_number `sn`	string	True	A sequence number used to determine message order within a stream. - If `useGlobalSequenceNumber` is false, this returns the gateway sequence number, which increments by one locally within each stream and resets on gateway restarts. - If `useGlobalSequenceNumber` is true, this returns the global sequence number, which uniquely identifies messages across the cluster. - A single cluster payload can be multiplexed into multiple stream payloads. - To distinguish each stream payload, a `dedupCounter` is included. - The returned sequence number is computed as: `cluster_sequence_number * 10^5 + dedupCounter`.
feed `f`	RfqFeed	True	The RFQ lifecycle event (NEW / EXPIRED / CANCELLED)
prev_sequence_number `ps`	string	True	The previous sequence number that determines the message order

Name `Lite`	Type	Required `Default`	Description
event `e`	RfqEvent	True	The RFQ lifecycle event: NEW, EXPIRED, or CANCELLED. On EXPIRED/CANCELLED only rfqID is populated; the platform then auto-cancels the maker's private quotes bound to this RFQ
rfq_id `ri`	string	True	The RFQ this event refers to
instrument `i`	string	False `None`	The RFQ instrument. Must be kind = STABLE_PERP
size `s`	string	False `None`	Requested size, expressed in base asset decimal units. Zero-size = platform solicitation for missing public presence
side `s1`	RfqSide	False `None`	Present only if the taker disclosed direction; omitted = two-way request
expiry `e1`	string	False `None`	RFQ TTL. The timestamp after which Gravity expires the RFQ, expressed in unix nanoseconds

Value	Description
`NEW` = 1	a new maker channel was created
`EXPIRED` = 2	both channels were expired
`CANCELLED` = 3	both channels were cancelled
