Updated main.py with a working prototype of the timer

This working prototype is currently running in the RP2040 chip. The 'leave loop' question should be replaced with a conditional checking for the state of a pushbutton switch. The configuration of the Pomodoro will allow to change the duration of Pomodoros, breaks, and condition for long break.
