更优雅的el-radio-button实现方式

小鹿最近想要做一个类似于el-radio-button的一个组件，但是我发现官方的组件并不支持我自定义其中的内容，官方文档只给了一个label属性让我填入我所需要展示的label，所以我在这里自己写了一个公共组件，支持高度自定义，参数都可以传入。

代码实现

<template>
  <div class="binary-selector">
    <div v-if="label" class="selector-label">
      <span v-if="required" class="required">*</span>
      {{ label }}：
    </div>
    <el-radio-group
      v-model="selectedValue"
      @change="handleChange"
      class="radio-group"
      :style="{ width: width, height: height }"
    >
      <el-radio-button
        v-for="option in options"
        :key="option.value"
        :label="option.value"
        class="custom-radio-button"
      >
        <div class="radio-content">
          {{ option.label }}
          <div v-if="selectedValue === option.value" class="selected-corner">
            <img class="corner-triangle" src="../assets/icons/corner-triangle.svg" alt="" />
            <img class="check-mark" src="../assets/icons/check-mark.svg" alt="" />
