 * 提供倒计时器统一封装
 * @class CountDown
 * @param {Object} spec 选项
 * @param {Date} [spec.base] 矫正时间(ms)，如果需要用服务端时间矫正倒计时，使用此参数
 * @param {Date} [spec.target=Date.now() + 3000] 目标时间(ms)
 * @param {Number} [spec.interval=1000] 倒计时触发间隔(ms)
 * @param {Function} [spec.onChange] 倒计时触发变更的事件回调
 * @param {Function} [spec.onStop] 倒计时结束的回调
 * @example
 * import { CountDown } from '@spore-ui/tskit';
 * const target = Date.now() + 5000;
 *
 * const cd1 = new CountDown({
 *   target,
 *   onChange(delta) {
