Teensy interface

Installation packages

On Raspberry PI 5 (running 64bit OS) Paho Mqtt can be installed with C++ support. This failed on Raspberry pi 4 (running 32 bit OK - due to Lidar support for YD Lidar S4B)

Install:

sudo apt install libpaho-mqtt-dev libpaho-mqttpp-dev mosquitto-dev mosquitto-clients

- in addition to other packages required for normal compile

This should allow the teensy interface to compile.
