Discoverability: Making the API easier to learn

[aaronsky]

The App Store Connect API is a complex beast, and while this library does good work around making authorization, paging, and uploading easier, the learning curve of the API itself is still quite high. I'd like to do some research to see how to improve the wrapper around the API to make it friendlier to Swift devs, either at the codegen level or through helpers created at the library level.
