IGDB has updated from version 2 to version 3 of their API. With this update comes several changes that need to be adopted in this package.

• Data structure changes including field renaming.
• Expand parameter is deprecated.
• Sroll API is deprecated.
• Filters are now facilitated through the Apicalypse query language.
• New error messages

Migration from v2 to v3 will make breaking changes.
