Allow dataset parsing to extract options from dataset (e.g. labels, colors, ...)

### Feature Proposal

I'm feeding this type of data-set to Chart.js:

```js
dataset= [
data: [
['people' => 'name' , 'x-axis' => 'yyyy-dd', 'y-axis' => 35 ],
['people' => 'other name' , 'x-axis' => 'yyyy-dd', 'y-axis' => 35 ],
],
'parsing': [ 'xAxisKey': 'x-axis', 'yAxisKey' : 'y-axis', ],
];
```
Unfortunately, 'parsing' only allow for 'xAxisKey' and 'yAxisKey' parsing. It would be interesting to allow for things like label (and color, etc.) to be extracted from data columns.

The goal is to create a stacked bar chart with each 'people' value having a different color using the autocolors plugin.
