* 分割数据，用于处理在一组点数据中，y 对应的数值存在 null/undefined/NaN 的情况
* 应用于折线图、区域图以及路径图
*
* ```typescript
* // return [[{x: 1, y: 2}, {x: 3, y: 3}]]
* getPathPoints([{x: 1, y: 2}, {x: 2, y: null}, {x: 3, y: 3}], true);
* // return [[{x: 1, y: 2}], [{x: 3, y: 3}]]
* getPathPoints([{x: 1, y: 2}, {x: 2, y: null}, {x: 3, y: 3}], false);
* // return [[[{ x: 1, y: 10 }, { x: 2, y: 2 }], [{ x: 9, y: 34 }, { x: 1, y: 1 }]]]
* getPathPoints([
* [{ x: 1, y: 10 }, { x: 2, y: 2 }],
* [{ x: 4, y: 2 }, { x: 8, y: NaN }],
* [{ x: 9, y: 34 }, { x: 1, y: 1 }],
* ], true);
* ```

* @param points 要进行处理点集合
* @param connectNulls 是否连接空值数据
* @param showSinglePoint 是否展示孤立点
* @returns 返回处理后的点集合
