4.2.0

Added FixedDurationBar which is great for visualizing tasks with a fixed duration whereas ProgressBar works best for tasks with an unknown duration.

protected override void Start()
{
	var options = new ProgressBarOptions
	{
		ForegroundColor = ConsoleColor.Yellow,
		ForegroundColorDone = ConsoleColor.DarkGreen,
		BackgroundColor = ConsoleColor.DarkGray,
		BackgroundCharacter = '\u2593'
	};
	var wait = TimeSpan.FromSeconds(25);
	using (var pbar = new FixedDurationBar(wait, "", options))
	{
		var t = new Thread(()=> LongRunningTask(pbar));
		t.Start();

		if (!pbar.CompletedHandle.WaitOne(wait))
			Console.Error.WriteLine($"{nameof(FixedDurationBar)} did not signal {nameof(FixedDurationBar.CompletedHandle)} after {wait}");

	}
}

private static void LongRunningTask(FixedDurationBar bar)
{
	for (var i = 0; i < 1_000_000; i++)
	{
		bar.Message = $"{i} events";
		if (bar.IsCompleted) break;
		Thread.Sleep(1);
	}
}
