StopwatchModel class
A stopwatch model that counts up from zero.
The stopwatch counts elapsed time, ticking at interval intervals. Unlike a timer, the stopwatch counts up and has no timeout.
Example:
final stopwatch = StopwatchModel();
final (model, cmd) = stopwatch.init();
// Start the stopwatch
final (model2, cmd2) = model.startCmd();
