Migrate more uses of ipnetwork types to oxnet types

[ahl]

• moves uses of IpNetwork, Ipv4Network, and Ipv6Network to IpNet, Ipv4Net, and Ipv6Net
• adds the crates imperative to relevant generate_api! invocations to automatically use oxnet types
• cleans up generate_api! uses by removing unneeded derives and sorting types
• removes the ipnetwork dep from Cargo.toml files where possible and sorts deps
