MaxMind integration

[duncanmcclean]

We should integrate MaxMind which is a helpful platform used by lots of people who sell digital products to help them protect against credit card chargebacks which can end up costing store owners a lot of money.

MaxMind provides a PHP SDK which we could use to hook into their service - https://github.com/maxmind/minfraud-api-php

Implementation

• We would have a configuration file for the digital products addon and we would have a boolean set of if the user wants to use the built-in MaxMind integration.
• If enabled, we would then send MaxMind reporting information about the customer which could be used to decide if the checkout goes through and if the checkout flow gets cancelled due to any flags being brought up.
