Getter for ExpirationIntent value is missing.

[cmeddins-e2g]

Thank you and your contributors for all your work to date. We are reviewing laravel-in-app-purchases package for one of our development projects. We're currently focusing on the Apple client and so far it looks great!
We noticed recently that there is currently no public getValue() for the ExpirationIntent. Fortunately it doesn't affect our initial release but we would appreciate an update to make the value accessible.

There is already an open PR that addresses the issue:
#12

Thanks!

• Supporting the new events.
• Adding deprecation messages and replacements.

And Enhancing the development experience allowing the back-end developer to complete his work without a need for purchase receipts from the mobile application.🚀
