   ### What problem does this feature solve?
   
   场景：一个网站受攻击的地图飞线效果，新的攻击数据来后，添加飞线，setOption 后，之前未执行完的动画直接被重置了

   ### What does the proposed API look like?
   
   ```
   series: [
       {
         id: 2,
         type: 'lines',
         coordinateSystem: 'geo',
         silent: true,
         effect: {
           show: true,
           trailWidth: 2,
           trailOpacity: 0.5,
           trailLength: 0.02,
           period: 3,
           symbol: 'arrow',
           symbolSize: 6,
           loop: false,
         },
         blendMode: 'source-over',
         lineStyle: {
           width: 2,
           color: function (params: { value?: [number[], number[], string] }) {
             return params.value?.[2] || 'rgb(255,183,45)'
           },
           curveness: 0.5,
         },
         zlevel: 1,
         animation: true,
         animationDuration: 3000,
         /** 添加配置项，实现增量数据动画，原有数据动画继续执行 */
         animationIncrementalUpdate: true,
         data: [],
       },
   ]
   ```
