Implemented the faster /geo call

... as can be found on http://ipinfo.io/developers

This is already implemented. Here is the code I use:

    $ipInfo = new Ipinfo();
    $ip = '127.0.0.1';
    $host = $ipInfo->getSpecificField($ip, Ipinfo::GEO);
    $city = $host->getCity();
    $state = $host->getRegion();
    $country = $host->getCountry();

You are totally right, but it isn't that clear in my opinion. Will be better to make a sort of stub call for this in my opinion. I modified my PR and improved the readme.

Hi @rvanlaak, thanks for the interest in this project. 😄
Did you try to test it with phpunit? It seems they added the postal field that is not yet documented. Can you confirm this? Thanks. 🍰

@rvanlaak can you please rebase your PR in one commit?

[rvanlaak]

Rebased the commits, left the documentation commit a separate one. Will test the postal for you later today

Thanks @rvanlaak ! You rock 🎸
