Slight extension of the original countdown face by Wesley Ellis.
- Press the light button to enter setting mode and adjust the
countdown timer.
- Start and pause the countdown using the alarm button, similar to the
stopwatch face.
- When paused or terminated, press the light button to restore the
last entered countdown.
