Does not work with mosquitto 1.6.x broker

[smuellener]

When we use this library to connect to mosquitto v 1.4.x and 1.5.x it works fine. When we try to connect to mosquitto 1.6.x broker, the connection can not be established. Is this problem known? Does https://github.com/victorclaessen/mqtt-LabVIEW solve this problem? Thank you

mosquitto 1.6.x switched to using the MQTTv5. I assume this is where the problem lies. Unfortunately, I do not have the time to look at this right now. Maybe someone else will pick this up, otherwise I hope that I will get to it in the coming weeks.
