espresso_machine_controller_v1.2

This is a WIP auto installer with a GUI, using Arduino CLI with the goal of not forcing the user to bloat their machine with the Arduino IDE. I have barely tested this, I'm cheap so I only have a handful of off brand ATMEGA Arduino Nanos.

I have added the schematic and a detailed assembly writeup to "README.md"; this build isn't 100% final but it is working and should work on specified espresso machine pumps.

This is just a release of the code and parts list, instructions aren't all inclusive and there isn't a wiring diagram yet.
