Added output 'optionsError'

[trajnisz]

Added output 'optionsError' to give control over error handling in .setOption(). This could be beneficial especially when options are set dynamically in application. It gives opportunity to inform with custom error about incorrect options or to somehow change options dynamically again.

Simple usage example:
HTML:

<div echarts [options]="chartOption" (optionsError)="onOptionsError($event)"></div>

TS:

  chartOption: EChartOption = {
    xAxis: {
      type: 'category',
      data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
    },
    series: [
      {
        data: [820, 932, 901, 934, 1290, 1330, 1320],
        type: 'line',
      },
    ],
  };

  onOptionsError(error){
    console.log('do something'); // We will get error because no yAxis is specified
  }
