chinese wechat (weixin) url tracking param about rules

[groundcat]

A more comprehensive version of rules for WeChat URLs:

"wechat":{
      "urlPattern":"^https?:\\/\\/(?:[a-z0-9-]+\\.)*?qq\\.(cn|com)",
      "rules":[
        "chksm",
        "key",
        "uin",
        "devicetype",
        "exportkey",
        "mpshare",
        "scene",
        "srcid",
        "nettype",
        "from",
        "subscene",
        "clicktime",
        "enterid",
        "sharer_sharetime",
        "sharer_shareid",
        "ver",
        "signature",
        "timestamp",
        "src"
      ]
    }

This rule has been tested without issues. I can confirm that the only necessary parameters are __biz, mid, idx, sn.
