Add animation;

[james-zhang-gb]

Add dynamic update option feature;

• use:SetOptionUpdater() and then send Chart into the chan;

example:

func example() {
	bar := charts.NewBar()
	anime := opts.Anime{
		Animation: true,
	}
	bar.SetGlobalOptions(
		charts.WithTitleOpts(opts.Title{
			Title: "datazoom options(inside)",
		}),
		charts.WithDataZoomOpts(opts.DataZoom{
			Type:  "inside",
			Start: 10,
			End:   50,
		}),
		charts.WithAnimationOpts(anime),
	)

	bar.SetXAxis(weeks).
		AddSeries("Category A", generateBarItems(), charts.WithSeriesAnimationOpts(anime)).
		AddSeries("Category B", generateBarItems(), charts.WithSeriesAnimationOpts(anime))
	updater := bar.SetOptionUpdater()
	go func() {
		for {
			bar.MultiSeries[1].Data = generateBarItems()
			updater <- bar
			time.Sleep(3 * time.Second)
		}
	}()
	page := components.NewPage()
	page.AddCharts(bar)
	// render to any writer
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		page.Render(w)
	})
	http.ListenAndServe("localhost:8089", nil)
}

Hi @james-zhang-gb, sorry for the late back to review this changes.
I think it could be an extension for go-echarts.
The websocket part is not part of the go-echarts core since it is more like the server/communication part instead of render chart itself. But it is actually a nice feature.
If you were willing to make it as an Extension for go-echarts.
Please let me know, I could work with you to finish it and also create an individual repo in go-echarts for this, or being maintained in your side it also fine.
