请问区间条形图是否支持同一个坐标轴下多个区间数据🤔 [FEATURE]

### 🐛 Question description [Please make everyone to understand it] ~FEATURE

demo上的区间柱状图仅支持单一区间，不知道是否支持多个区间的能力？
如图所示，在某一坐标轴下，支持多个区间的数据展示，并且每个区间之间不连续。
例如下图：分类一有三个区间：[40,50],[76,100],[120,150]，绘制在图表上的效果则是有三个条形

### 🏞 Expected result

* **G2Plot Version**:
* **Platform**:

Start with the range bar example at https://g2plot.antv.vision/zh/examples/bar/range#basic and trace the related chart entry point and data configuration. Determine how multiple non-contiguous intervals for one category should be represented, then verify that the chart renders separate bars for intervals such as [40,50], [76,100], and [120,150].
