Raspberry Pi Pico Stopwatch (TM1637 + 2 Buttons + Buzzer)

Press, count, take a lap! We are building a stopwatch with hundredths on a Raspberry Pi Pico. The TM1637 display shows seconds and hundredths below one minute, then minutes and seconds. The START button starts and stops it, the LAP button takes a lap: LAP1 and that lap's time appear while the count keeps running. On reset the best lap is shown, and a buzzer confirms every action with a short beep.
