鸿蒙ArkUI实现开关switch组件

鸿蒙ArkUI官方提供的toggle组件实现了开关的样式，但在使用过程中还是非常的不方便。

DIY可视化对鸿蒙ArkUI实现开关switch组件扩展后满足基本的switch需求，支持绑定值、设置标题文本、整个背景样式等。

/**
 * 开关

@Component
export default  struct DiygwSwitch{
  //绑定的值
  @Link value:number;
  //未选中图标
  @State labelImg: Resource = $r('app.media.user');
  //是否文本图片
  @State isLabelImg: boolean = false;
  @State labelImgWidth: number = 20;
  @State labelImgHeight: number = 20;
  //标题文本
  @State label:string = '开关';
  //水平状态时，文本占大小
  @State labelWidth:number = 80;
  //是否标题文本换行
  @State isWrapLabel:boolean = false;
  //是否标题文本
  @State isLabel:boolean = true;
  //标题颜色
  @State labelColor:string = "#333333";
  //自动标题长度
  @State isLabelAuto:boolean = false;
  //文本字体大小
  @State textSize:number = 14;
  //选中图版本大小
  @State imgSize:number = 28;
  //组件内边距
