Updating the script for use with Meshtastic 2.0 protobufs?

[jeremiah-k]

Nice work here!

I was hoping to work with the mqtt json mode in a new project I'm working on Meshtastic <-> Matrix Relay, but the Meshtastic devs are saying the current json implementation is unstable and shouldn't be used. If we were able to get this working with the latest protobufs, we'd work to add native MQTT support.

I cloned your repo and am looking at compiling the most recent Meshtastic protobufs & updating your script, but I'm not having much luck yet.

Would it take a lot of work to make this script compatible with the current protobufs? I think a good number of people would still get use out of it.
