update amazon IAP compile time dependency

* Remove dependency `in-app-purchasing-2.0.1.jar` which is from 2015, and instead compile against its replacement `amazon-appstore-sdk` v3.x. This change currently makes no difference at compile time, as this crash was only encountered at runtime, but still good to update this dependency to what users are more likely to be currently using.
