APICloud AVM 封装日期和时间选择组件

因项目中很多表单要用到日期选择和时间选择的内容，所以基于picker封装了日期和时间选择的组件。

datePicker
组件内的年份是取得举例今年100年以内的年份，可根据时间需要进行扩容或缩减，月份是12个月固定的，每月的天数，根据所选年份和月份进行获取。默认设置当前日期。
<template>

    <text class="picker-label">{dateDesc}</text>
</picker>

timePicker
时、分、秒都是固定的，组件初始是默认的当前时间。

组件使用
如果一个页面中，同一组件多次使用，一定要注意要把组件ID进行区分。每个组件的ID通过当前页面传入组件。组件中通过props进行接收。
<template>

<scroll-view class="page">
    <safe-area></safe-area>
    <view class="item">
        <text class="item-label">日程主题</text>
