Add a `ronin refang` command

[postmodern]

As a counterpart to #204, there should also be a ronin refang command which re-fangs previously defanged URLs, host names, and IPs.

• hxxps://www[.]evil[.]com/foo/bar/baz -> https://www.evil.com/foo/bar/baz
• www[.]example[.]com -> www.example.com
• 192[.]168[.]1[.]1 -> 192.168.1.1

This command should inherit from ValueProcessorCommand so that it can process URLs or IPs as both command-line arguments and via the --file option.

This should use the new Ronin::Support::Network::Defang module in the ronin-support 1.2.0 branch.
