Stop throwing AddressNotFoundException when an address can't be found.

This is part of the API and is unlikely to be changed before a new major release, which may never happen. As discussed in #12, if you are getting many of these exceptions, you likely have an integration issue.

That said, we might consider a PR for corresponding Try... methods in the spirit of TryParse.

Agree with this, exceptions shouldn't be used for flow control.

There are several reasons why the IP might not be valid and if there's no information then it's just a null or lack-of-info response. Even maxmind states that not every IP is included in the database which means there are valid IPs that still throw an error which doesn't make sense.

I'll submit a PR for this.

Closed by #50.
