Qos not respected on subscription

[rafaelnobrekz]

Hi! Starting to know the library, I noticed that qos1 is hardcoded on MqttSubscription? Does this make sense ?

public func subscribe(_ topic: String, qos: CocoaMQTTQoS = .qos1) {
        let filter = MqttSubscription(topic: topic)
        return subscribe([filter])
    }

It's OK, It's swift syntax to set default values.

Hi, what I mean is the qos variable is not injected into MqttSubscription object thus what we set is completely ignored

Cool, thanks! I could have made a PR, but I thought maybe I was missing something 🤪
