Gateway capability mask

[erkinalp]

As documented at https://discord-userdoccers.vercel.app/topics/gateway#gateway-capabilities and extending from them:

Value	Name	Description
1 << 0	LAZY_USER_NOTES	Removes the notes field from the Ready event,
1 << 1	NO_AFFINE_USER_IDS	Prevents member/presence syncing and Presence Update events for implicit relationships
1 << 2	VERSIONED_READ_STATES	Enables versioned read states, changing the read_state field in the Ready event to an object, allowing it to be cached when re-identifying
1 << 3	VERSIONED_USER_GUILD_SETTINGS	Enables versioned user guild settings, changing the user_guild_settings field in the Ready event to an object, allowing it to be cached when re-identifying
1 << 4	DEDUPE_USER_OBJECTS	Dehydrates the Ready payload, moving all user objects to the users field and replacing them in various places in the payload with user_id or recipient_id, and merging the members fields of all guilds into a single merged_members field
1 << 5	PRIORITIZED_READY_PAYLOAD	Separates the Ready payload into two parts (Ready and Ready Supplemental) allowing the client to receive the Ready payload faster and then receive the rest of the payload later; depends on DEDUPE_USER_OBJECTS
1 << 6	MULTIPLE_GUILD_EXPERIMENT_POPULATIONS	Changes the populations entry of guild_experiments in the Ready event to be an array of populations rather than a single population
1 << 7	NON_CHANNEL_READ_STATES	Includes read states tied to non-channel resources (e.g. guild scheduled events and notification center) in the read_states field of the Ready event
1 << 8	AUTH_TOKEN_REFRESH	Enables auth token refresh, allowing the client to optionally receive a new auth token in the auth_token field of the Ready event
1 << 9	USER_SETTINGS_PROTO	Removes the user_settings field from the Ready event, and prevents User Settings Update events; the user_settings_proto field and User Settings Proto Update event is used instead
1 << 10	CLIENT_STATE_V2	Enables client state caching v2
1 << 11	PASSIVE_GUILD_UPDATE	Enables passive guild updates, allowing the client to receive Passive Update v1 events instead of Channel Unreads Update events for guilds it is not subscribed to
1 << 12	CALL_SIGNALLING_OVER_WS	Enables CALL_CREATE and CALL_DELETE events over WebSockets
1 << 13	BULK_REACTION_ADD_REMOVE	Enables MESSAGE_REACTION_ADD_MANY and MESSAGE_REACTION_DELETE_MANY events
1 << 47	CUSTOM_START
1 << 48	NO_ECHO	Do not send the connecting user's own events
1 << 49	LATENCY_COMPENSATION	Actively try to compensate for network latency, aiming for a fixed latency rather than sending the events as fast as possible
1 << 50	LIVE_COMPOSITION_ENABLED	Receive others' live composed messages. If not asserted, live-composed messages will be communicated as series of edits
1 << 51	PUBLIC_READ_RECEIPTS	Send public read states
1 << 52	MULTI_GUILD_CHANNELS	Changes channel property in the guild channels from a channel ID to an array of channel IDs
1 << 53	DEDUPE_MULTI_GUILD_MESSAGES	De-dupe messages appearing in multiple channels due to custom message routing (#291)
1 <<63	FEDERATION_FORMAT	Send the gateway response in S-S format (#1035)
