CountDownManager class

倒计时管理器（单例）

用于管理多个倒计时实例，支持同时运行多个倒计时，每个倒计时可以设置不同的时长和显示格式。

使用示例：

class GlobalCoundDown {
  static final GlobalCoundDown _instance = GlobalCoundDown._internal();
  static GlobalCoundDown get instance => _instance;
  factory GlobalCoundDown() => _instance;
  GlobalCoundDown._internal();

  final countDownManager = CountDownManager();

  var homeGiftCountDownId = 'homeGiftCountDown';
  var homeGiftCountDownStr = '00:00'.obs;
  var homeGiftCountDownMaxTime = 10 * 60;

  void startHomeGiftCountDown() {
    countDownManager.createCountDown(
      id: homeGiftCountDownId,
      maxSeconds: homeGiftCountDownMaxTime,
      format: CountDownFormat.mmss,
      onUpdate: (timeStr) {
        homeGiftCountDownStr.value = timeStr;
      },
      onComplete: () {
        homeGiftCountDownStr.value = '00:00';
        countDownManager.disposeCountDown(homeGiftCountDownId);
      },
    );
    countDownManager.startCountDown(homeGiftCountDownId);
  }
}
