Currently, the JsonSchema trait is derived instead of manually implemented to match the parser for IpNet, IpV4Net, and IpV6Net.
This causes it to generate a schema object that indicates that for IpV4Net, the serde deserializer expects a JSON object like:

{
    "addr": "0.0.0.0",
    "prefix_len": 0
}

when in reality, the deserializer expects, and serializer produces:

"0.0.0.0/0"

This can be resolved by implementing JsonSchema manually
