Adding syntax sugar of IP range judgment for bloblang

[jicanghaixb]

Now i manipulation data by powerful Bloblang！the configuration syntax is very concise. At present, they are very perfect. Except for one problem, they do not support the judgment of IP range(ipv4/ipv6). This limits the data processing with IP condition. maybe refer to beats(https://github.com/elastic/beats/blob/master/libbeat/conditions/network.go) to implement a network() method syntax sugar.

example:
root.contain_ip = this.ip.neworks('192.168.1.0/24', '10.0.0.0/8', loopback)

In: {"ip":"192.168.1.10"}

Out: {"contain_ip":true}
