[feature request] make BLPop return a Channel

[Asalle]

Hey, thank you for the amazing project! I remember Subscribe used to block, and now it returns a Channel, which is so much cooler. Can it be also done for BLPop?

Our use case is as following:

func getItem(){
    ctx := makeContext()
    go func(){
        item := redis.BLPop()
        // some more code
        switch {
            case <-ctx.Done(): return
        }
    }
}

As you can see, now we have 2 places where function can be blocked. Wouldn't it be neat to have it all in the switch?

func getItem(){
    ctx := makeContext()
    go func(){
        switch {
            case <-ctx.Done(): return
            case item <- redis.BLPop().Channel():
                 // do stuff with item
        }
    }
}

This would be a workaround to https://github.com/redis/go-redis/issues/2556
