ts-dns 日志显示，因为 AAAA 类型查询不返回 ipv4，所以被当做 clean 处理，即使域名符合 gfwlist 也不会再次进行查询

INFO[0001] [0x4e1c] [server.go:238] cn/empty ipv4, group: clean  QUESTION=www.google.com. Q_TYPE=AAAA SRC="192.168.0.95:53871"
INFO[0003] [0xc9c1] [server.go:244] match gfwlist, group: dirty  QUESTION=www.google.com. Q_TYPE=A SRC="192.168.0.95:60054"

目前暂时通过在dirty组中用rules规定google.com强制走该组解析解决，但是我觉得这个判断逻辑是不是应该针对 AAAA 记录查询修改一下

即将发布的v1.0版本（#41）将修复这个问题。clean和dirty组将不再做特殊处理，匹配规则将由rules/gfwlist明确指定，并通过redirector进行更灵活的重定向（#25）。
新版本重构了大量代码，配置文件相比v0略有改动，欢迎review。
