// after we have the rest of the users. We will request the GUILD_MEMBERS_CHUNK information
// which will be sent from discord over the main Websocket and will be handled by
// GuildMemberChunkHandler. After the handler has received all users as determined by the
// value set using `setExpectedGuildMembers`, it will do one of the following:
// 1) If this is a Bot account, immediately call EntityBuilder#createGuildSecondPass, thus finishing
// the Guild object creation process.
// 2) If this is a Client account, it will request op 12 (GUILD_SYNC) to make sure we have all information
// about online users as GUILD_MEMBERS_CHUNK does not include presence information, and when loading the
// members from GUILD_MEMBERS_CHUNK, we assume they are offline. GUILD_SYNC makes sure that we mark them
// properly. After GUILD_SYNC is received by GuildSyncHandler, it will call EntityBuilder#createGuildSecondPass
//
//If we actually -did- get all of the users needed, then we don't need to Chunk. Furthermore,
// we don't need to use GUILD_SYNC because we always get presences with users thus we have all information
