+/**
+ * @supported Quantumult X (v1.0.8-build253)
+ * Shawn @XIAO_KOP
+ * 功能： 将不同格式订阅转换成 Quantumult X，并支持简单的过滤.
+ * 目前仅支持 V2RayN 格式的订阅，以及 quanx 格式写法的节点引用；
+ * 过滤参数为 in,out, 分别为保留与排除，多个参数间用+号连接，建议将所有参数 url-encode
+ * 示范，
+0⃣️ 在quantumult X 配置文件中[general] 部分，加入 resource_parser_url=https://raw.githubusercontent.com/KOP-XIAO/QuantumultX/master/Scripts/resource-parser.js
+1⃣️ 原始订阅连接为: https://raw.githubusercontent.com/crossutility/Quantumult-X/master/server-complete.txt , 
+2⃣️ 想要保留的参数为 in=tls+ss, 想要过滤的参数为 out=http+2
+3⃣️ 则填入 quanx 的总链接为 https://dove.589669.xyz/all2quanx?&sub=https://jiang.netlify.com/#in=tls+ss&out=http+2
+4⃣️ 填入上述链接并打开的资源解析器开关
