Add reverse domain name notation property

[jvanasco]

A reverse domain notation function, as offered in #342

Thank you! I was picturing this as a new property. Rather than expand the entrypoints into this library. See cff0327. What do you think?

Interesting. LGTM as a property of ExtractResult and I can see how that makes sense for many use-cases!

Thanks for the contribution!

You're welcome!

FYI, I realized last night that I greatly prefer your idea to implement this as a property of ExtractResult. This isn't a true reverse domain notation - it's a slight adaptation of the concept (although it is what most people implement IRL) based on the TLD. As such, it makes much more sense as a property of the ExtractResult than a standalone function.

Good catch. I noted this in ffd6203.
