Feature Request: Support for TLS encrypted MQTT connection

[wolet-ft]

Is your feature request related to a problem? Please describe.
I am currently running an MQTT broker on port 8883, using TLS v1.2 encryption. The app currently cannot connect to this broker

Describe the solution you'd like
Please add support for TLS 1.2, TLS 1.3

Describe alternatives you've considered
There is no real alternative to encrypted connections nowadays.

Additional context
This change shall not be much effort. It mostly will consists of integrating existing TLS libraries.

Would be awesome. I think TLS is kind compulsory these days...

TLS is definitely necessary for today's security requirements. I would like to request that this feature be added.
