v1.0.0 release

This release breaks the program into subcommands:

1. `ip`
2. `update`

`ip` is meant to be a convenience function to quickly return your
public IP.

`update` is the original functionality of the program which takes a
required `--domain` flag and an optional `--subdomain` flag.

Because of the transition to subcommands this release is not
backwards compatible with previous releases. Please update any
existing invocations of the program to use the new `update` subcommand.
