 - [x] 支持对```CTGNET```、```CN2GIA```和```CN2GT```线路的判断
 - [x] 支持对```CMIN2```和```CMI```线路的判断
 - [x] 支持对整个回程路由进行线路分析，一个目标IP可能会分析出多种线路
- [x] 支持对主流接入点的线路检测，方便分析国际互联能力
- [x] 多次并发路由检测以分析平均多次路由，避免单次路由因网络波动未能准确检测
 - [x] 增加对全平台的编译支持，原版[backtrace](https://github.com/zhanghanyun/backtrace)仅支持linux平台的amd64和arm64架构
 - [x] 兼容额外的ICMP地址获取，若当前目标IP无法查询路由尝试额外的IP地址
