"Incorrect" data keys in legacy mode

[breadadams]

Recently switched over from freegeoip.net/xml/, appending the &legacy=1 param to the request. However the shape of the data returned isn't identical to the old data. For example, countryCode is now country_code.

Not sure if this something you would want to address at your API level (as I get the feeling freegeoip is the face of multiple APIs that have been deprecated), but I thought I'd create an issue anyway for anyone facing the same issue.
