可以支持查询国内和国外ip时分别指派不同的ip库吗 about ips HOT 1 OPEN

示例：
1. 下载 qqwry.dat & GeoLite2 数据库
    ips download qqwry.dat
    ips download GeoLite2-City.mmdb

2. 使用 hybrid-mode 查询 2 个数据库
    ips -i .ips/qqwry.dat -i .ips/GeoLite2-City.mmdb 12.12.12.12 -f '*' -j
    {"items":[{"ip":"12.12.12.12","net":"12.11.140.0/22","data":{"0_country":"美国","0_isp":"AT","1_accuracy_radius":"1000","1_city":"","1_continent":"北美洲","1_country":"美国","1_latitude":"37.751000","1_longitude":"-97.822000","1_province":"","1_registered_country":"美国","1_utcOffset":"America/Chicago"}}]}

    ips -i .ips/qqwry.dat -i .ips/GeoLite2-City.mmdb -f '*'  123.123.123.123 -j
    {"items":[{"ip":"123.123.123.123","net":"123.123.123.0/24","data":{"0_country":"**","0_isp":"联通","1_accuracy_radius":"1000","1_city":"北京","1_continent":"亚洲","1_country":"**","1_latitude":"39.911000","1_longitude":"116.395000","1_province":"北京","1_registered_country":"**","1_utcOffset":"Asia/Shanghai"}}]}
