This commit refactors the whole package gateway as well as utils/ws (formerly utils/wsutil) and voice/voicegateway. The new refactor utilizes a design pattern involving a concurrent loop and an arriving event channel. An additional change was made to the way gateway events are typed. Before, pretty much any type will satisfy a gateway event type, since the actual type was just interface{}. The new refactor defines a concrete interface that events can implement: type Event interface { Op() OpCode EventType() EventType } Using this interface, the user can easily add custom gateway events independently of the library without relying on string maps. This adds a lot of type safety into the library and makes type-switching on Event types much more reasonable. Gateway error callbacks are also almost entirely removed in favor of custom gateway events. A catch-all can easily be added like this: s.AddHandler(func(err error) { log.Println("gateway error:, err") })
