Fast IP to CIDR lookup in Golang

 The cidranger library provides fast IP to CIDR block(s) lookup using
 path-compressed prefix tries in Golang, inspired by IPv4 route lookup in
 Linux.
 Possible use cases include detecting if a IP address is from published
 cloud provider CIDR blocks (e.g. "is 52.95.110.1 contained in AWS Route
 53 CIDR 52.95.110.0/24?"), IP routing rules, etc.
