Python chnroutes Ros Edition

Chnroutes estimated that many people know the network. It's pretty good. Automatically update the routing table script.

Squeeze a little bit of time to simply revise it a bit. It supports the generation of RouterOS scripts, which makes it easy for the soft router to do the IP auto-select line.
Note that the script clears the original address list china_address_lists
