* @arg {Boolean} [options.compress=false] Whether to request WebSocket data to be compressed or not
* @arg {Number} [options.connectionTimeout=30000] How long in milliseconds to wait for the connection to handshake with the server
* @arg {Object} [options.disableEvents] If disableEvents[eventName] is true, the WS event will not be processed. This can cause significant performance increase on large bots. [A full list of the WS event names can be found on the docs reference page](/Eris/docs/reference#ws-event-names)
* @arg {Boolean} [options.disableEveryone=true] When true, filter out @everyone/@here by default in createMessage/editMessage
* @arg {Number} [options.firstShardID=0] The ID of the first shard to run for this client
* @arg {Boolean} [options.getAllUsers=false] Get all the users in every guild. Ready time will be severely delayed
* @arg {Number} [options.guildCreateTimeout=2000] How long in milliseconds to wait for a GUILD_CREATE before "ready" is fired. Increase this value if you notice missing guilds
* @arg {Boolean} [options.guildSubscriptions=true] If false, disables some guild subscription events, including typing and presence events. This will reduce processing load, but will also result in inconsistent member caching
* @arg {Number} [options.largeThreshold=250] The maximum number of offline users per guild during initial guild data transmission
* @arg {Number} [options.latencyThreshold=30000] The average request latency at which Eris will start emitting latency errors
* @arg {Number} [options.lastShardID=options.maxShards - 1] The ID of the last shard to run for this client
* @arg {Number | String} [options.maxShards=1] The total number of shards you want to run. If "auto" Eris will use Discord's recommended shard count.
* @arg {Number} [options.messageLimit=100] The maximum size of a channel message cache
* @arg {Boolean} [options.opusOnly=false] Whether to suppress the node-opus not found error or not
* @arg {Number} [options.ratelimiterOffset=0] A number of milliseconds to offset the ratelimit timing calculations by
* @arg {Number} [options.requestTimeout=15000] A number of milliseconds before requests are considered timed out
* @arg {Boolean} [options.restMode=false] Whether to enable getting objects over REST. This should only be enabled if you are not connecting to the gateway. Bot tokens must be prefixed manually in REST mode
* @arg {Boolean} [options.seedVoiceConnections=false] Whether to populate bot.voiceConnections with existing connections the bot account has during startup. Note that this will disconnect connections from other bot sessions
* @arg {String} [options.defaultImageFormat="jpg"] The default format to provide user avatars, guild icons, and group icons in. Can be "jpg", "png", "gif", or "webp"
* @arg {Number} [options.defaultImageSize=128] The default size to return user avatars, guild icons, banners, splashes, and group icons. Can be any power of two between 16 and 2048. If the height and width are different, the width will be the value specified, and the height relative to that
* @arg {Object} [options.ws] An object of WebSocket options to pass to the shard WebSocket constructors
* @arg {Object} [options.agent] A HTTP Agent used to proxy requests
* @arg {Number} [options.maxReconnectAttempts=Infinity] The maximum amount of times that the client is allowed to try to reconnect to Discord.
