Bundle libmaxminddb

[josh]

Hey @dbussink, question/idea. Is there any reason this gem can't bundle libmaxminddb instead of relying on it externally? Would it be ridiculously big?

This is 1 of 2 external gem libs used by github. And we're trying to get icu bundled for charlock_holmes brianmario/charlock_holmes#82.

wdyt?

It's not a huge library so that should be possible I think. What's the value / goal here? More isolated builds / independent gems?

[josh]

Yeah, you won't need to have libmaxminddb installed. gem install geoip2_compat will pretty much always work.
