Add Documentation for the system state machine to
a) understand the state machine better
b) implement a error state handler
c) allow for easier understandability

Refactor all function names to be more descriptive on
a) what the function implements
b) what the functions objective is
c) what the function gets/sets/handles

ie. heater_driver__set_output_on explains imperative what happens here.

Objective is to get the code more module based, so each module has a single and defined purpose.
(ie. move everything that handles a human interface to a hid-"class")

Target is to improve initial overshooting when heating up from cold.

To implement a on-screen menu, setpoint saving, PID tuning.. a persistant storage is required.
marcs-opensolder pcb does not have a footprint for an EEPROM.

Consider
a) add an I2C eeprom to the i2c extension header
b) backpack-solder a EEPROM chip to PCB temp sensor (could have negative influences on temperature readings)
c) add a SD card to display SPI port - maybe overkill to store temp values.

Implement safety functionality, i.e. timeouts, overheat checks in low level code,
Implement the Watchdog-Timer

Objective - don't burn my house down when forgetting to power off the unit
