wrong type of parameter 'id' of LegendOptions.item.onclick

[bb-in-hoodie]

Description

tested using the example code in Legend Template1 example

even though the parameter id of LegendOptions.item.onclick is defined as DataItem type, it actually is a string type value which shows the id of a selected legend item.

options.d.ts > LegendOptions > item

onclick, onover, onout share the same parameter type.

Steps to check or reproduce

// base css
import 'billboard.js/dist/theme/insight.css';
import bb from 'billboard.js';

// for ESM environment, need to import modules as:
// import bb, {pie} from "billboard.js"

var chart = bb.generate({
  data: {
    columns: [['data1', 100], ['data2', 300], ['data3', 200]],
    type: 'pie' // for ESM specify as: pie()
  },
  legend: {
    contents: {
      bindto: '#legend',
      template:
        "<span style='color:#fff;padding:10px;background-color:{=COLOR}'>{=TITLE}</span>"
    },
    item: {
      onclick: id => console.log(id)
    }
  },
  bindto: '#legendTemplate1'
});
