Rewrite-Parser.beta.js

/***************************
支持将 QX重写 Surge模块 Loon插件 解析至Surge Shadowrocket Loon Stash

远程重写支持多链接输入，链接间用😂连接 可以 重写 模块 插件 混合传入

说明
原脚本作者@小白脸 脚本修改@chengkongyiban
感谢@xream 提供的replace-Header.js
               echo-response.js
感谢@mieqq 提供的replace-body.js
插件图标用的 @Keikinn 的 StickerOnScreen项目 以及 @Toperlock 的图标库项目，感谢
