New version?

So I have time to work with that lib again, but I need to know what I can improve. It seems that there is an incompatible version between react and mqttjs. I will be analyzing in the next few days and trying to correct these errors. Maybe, there is a version 3.0.0 with the code all refactored

We have a problem, the mqtt@4.3.7 version doesn't support webpack 5 yet. There's another lib that solves this but I haven't tested it yet, it's https://github.com/ashiqdey/precompiled-mqtt I will test and send as alpha version 3.0.0@alpha.3
