- Create class 'evaluatedJoystick'
- evaluates a joystick with 2 analog signals
- scales the adc input to coordinates with detailed tolerances
- calculates angle and radius
- defines an enum with position information
- Add joystick configuration and class instance to config.cpp
- Add code for testing the new class to main.cpp
- Add joystick.cpp to cmakelists
now function `joystick.getData` can be used globally to obtain a struct with
current position data of the joystick
