Bump to echart-v5.3

[zbjdonald]

Hi, Is there a plan to update echarts to version 5.3? I want to use the value_formatter to display return rates. Sample code worked in pyecharts:

line.add_xaxis(x_list).add_yaxis(column_name, column_data.tolist(),
                                 label_opts=opts.LabelOpts(is_show=False),
                                 yaxis_index=0 if column_name in left_y_labels else 1,
                                 tooltip_opts={'valueFormatter': JsCode(
                                     "(value) => value === null ? '-' : (value * 100).toFixed(2) + '%'")},
                                 is_symbol_show=False)

Same here, value_formatter would be really helpful for tooltip customization. Did you manage to solve it somehow else?

Usage

line.set_global_opts(title_opts=title_opts,
                     xaxis_opts=opts.AxisOpts(axisline_opts=opts.AxisLineOpts(is_on_zero=False)),

                     tooltip_opts=opts.TooltipOpts(
                         is_show=True, trigger="axis", axis_pointer_type="shadow",

                     ),
