Simplify installation

[buserp]

Currently, the T-Tree software needs to be installed on top of Puara, and although we have systemd units for this, the setup process is very manual.

Creating a ready-to-go image for the T-Tree could be a good way to simplify the installation. Or create an install script that handles everything for you.

From lightest to heaviest, some potential ways to do this:

1. Create script that automates T-Tree software install on top of a clean Puara install
2. Create fork of Puara that installs T-Tree software and enables I2C, GPIO, etc. (Maybe upstream this back to Puara image?)
3. Create image of T-Tree software based on custom Linux installation like DietPi, Yocto, Buildroot, Ubuntu IOT, etc.
