* ### Available since 2.0.0.
* ### UNSUBSCRIBE [channel [channel ...]]
*
* Unsubscribes the client from the given channels, or from all of them if none is given.

* to the client.
* ### Return value
* Appears to be an array. The 'unsubscribe' keyword followed by the list of subscribed
* channels and then the count of those channels.
