Starting to explore Maxmind API decoupling (Signature clashes)

[benjaminpick]

I don't want to extend Maxmind classes anymore (or as less as
possible/reasonable), instead wrapping them with my own types.

• My readers should always return my City model
• This means, the Maxmind Reader class in manual.php needs to be wrapped
• Can the model stay extended?

Reason: PHP 7 Typing is helpful, but when different plugins use different versions of the Maxmind library, everything goes downhill.

I guess long-term we will need to use something like php-scoper...
