这里应该也要考虑触发hls muxer开启
也即HTTPTS sub需要使用hls muxer，hls muxer开启和关闭都要考虑HTTPTS sub

func (*Group) Dispose 

func (group *Group) Dispose()

主动释放所有资源。保证所有资源的生命周期逻辑上都在我们的控制中。降低出bug的几率，降低心智负担。 注意，Dispose后，不应再使用这个对象。 值得一提，如果是从其他协程回调回来的消息，在使用Group中的资源前，要判断资源是否存在以及可用。

TODO chef: 

后续弄个协程来替换掉目前锁的方式，来做消息同步。这样有个好处，就是不用写很多的资源有效判断。统一写一个就好了。
目前Dispose在IsTotalEmpty时调用，暂时没有这个问题。
