这是一个只用来检验ipv4 和 ipv6 Cidr掩码是否合法的包，比如：192.12.0.0/12 （合法） ， 192.12.0.0/11 （不合法）。 实现的依据是根据《计算机网络》书中cidr的掩码的概念

This is a package that only can be used to verify whether the ipv4、ipv6 Cidr mask is legal, such as 192.12.0.0/12 (legal) and 192.12.0.0/11 (illegal). The basis for implementation is based on the concept of CIDR mask in the book "Computer Network"

example：

const res = judgeIpv4CidrRule('192.12.0.0/12 ') // res = true const res = judgeIpv4CidrRule('192.12.0.0/11 ') // res = false

const res = judgeIpv6CidrRule('2000::/8') // res = true const res = judgeIpv6CidrRule('1::/3') // res = false
