wqzwh opened a new issue #8495: dataset中的source配置项希望能得到扩展

   ### One-line summary [问题简述]
   ``` javascript
   dataset: {
           dimensions: ['product', 'count', 'score'],
           source:{
               'product': ['Matcha Latte', 'Milk Tea', 'Cheese Cocoa', 'Walnut Brownie'],
               'count': [823, 235, 1042, 988],
               'score': [95.8, 81.4, 91.2, 76.9],
           }
       }
   ```
   以上配置中的count和score，只支持纯数组，希望能是数组对象的形式(类似series中的data配置写法)，因为在实际应用场景需要携带其他数据信息例如：
   ``` javascript 
   'count': [{
        value: 823,
        other1: 'string',
        other2: 'string'
   },{
        value: 235,
        other1: 'string',
        other2: 'string'
   },{
        value: 1042,
        other1: 'string',
        other2: 'string'
   },{
        value: 988,
        other1: 'string',
        other2: 'string'
   }]
   ```
   如果在series中的data这样配置那么在tooltip中的format能获取到携带的数据，方便做自定义格式化处理，所以希望dataset也支持这样
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:4.0
   + Browser version [浏览器类型和版本]:67
   + OS Version [操作系统类型和版本]:Mac 10.13.4 
   
   
   
   
   
   ### Expected behaviour [期望结果]
   
   如果在series中的data这样配置那么在tooltip中的format能获取到携带的数据，方便做自定义格式化处理，所以希望dataset也支持这样
   
   
   
   ### ECharts option [ECharts配置项]
   <!-- Copy and paste your 'echarts option' here. -->
   <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
   
   官网配置如下：
   ```javascript
   option = {
       legend: {},
       tooltip: {
           formatter(d) {
               console.log(d)
           }
       },
       dataset: {
           dimensions: ['product', 'count', 'score'],
           source:{
               'product': ['Matcha Latte', 'Milk Tea', 'Cheese Cocoa', 'Walnut Brownie'],
               'count': [823, 235, 1042, 988],
               'score': [95.8, 81.4, 91.2, 76.9],
           }
       },
       xAxis: {type: 'category'},
       yAxis: {},
       // Declare several bar series, each will be mapped
       // to a column of dataset.source by default.
       series: [
           {type: 'bar'},
           {type: 'bar'},
           {type: 'bar'}
       ]
   };
   
   ```
   
   希望支持的配置如下：
   ```javascript
   option = {
       legend: {},
       tooltip: {
           formatter(d) {
               console.log(d)
           }
       },
       dataset: {
           dimensions: ['product', 'count', 'score'],
           source:{
               'product': ['Matcha Latte', 'Milk Tea', 'Cheese Cocoa', 'Walnut Brownie'],
               'count': [{
                    value: 823,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 235,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 1042,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 988,
                    other1: 'string',
                    other2: 'string'
               }],
               'score': [{
                    value: 823,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 235,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 1042,
                    other1: 'string',
                    other2: 'string'
               },{
                    value: 988,
                    other1: 'string',
                    other2: 'string'
               }],
           }
       },
       xAxis: {type: 'category'},
       yAxis: {},
       series: [
           {type: 'bar'},
           {type: 'bar'},
           {type: 'bar'}
       ]
   };
   
   ```
