生成payload时，paramsCombination函数有拷贝问题

[jayus0821]

以命令注入插件为例
new_data = copy.deepcopy(data)应该放在for循环下，源代码在for循环外，导致result添加一组payload之后，下一次for循环，把上一组的new_data修改掉了，最后所有payload都是同一个，其实根本没有遍历payload.
`def paramsCombination(self, data: dict, place=PLACE.GET, url_flag={}, hint=POST_HINT.NORMAL, urlsafe='/\'):
result = []
payloads = url_flag.keys()

    for spli in ['', ';', "&&", "|"]:
        if place == PLACE.POST:
            if hint == POST_HINT.NORMAL:
                for key, value in data.items():
                    for payload in payloads:
                        new_data = copy.deepcopy(data)
                        print("payload : ",payload)
                        new_data[key] = spli + payload  #...
                        print("new_data : ",new_data)
                        print((key, value, payload, new_data, url_flag[payload]))
                        result.append((key, value, payload, new_data, url_flag[payload]))`
