/**
 * TG频道图片推送
 * @author: Peng-YM
 * 更新地址：https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tasks/telegram.js
 * 使用方法：
 * 1. 在channels里面添加频道的id，比如说对于频道https://t.me/ABCD，则填入"ABCD"
 * 比如 channels = ["ABCD", "CDEF"]
 * 2. 在maxMedias设置每个频道最多显示的图片数量，比如说设置为3，则只会显示最近3张图片。
 * 3. alwaysNotice控制是否重复显示已经看过的图片，如果设置为false，则只会显示更新的图片。
