Deferred deeplink 2.0: Parse for utm_source and utm_campaign in CR

[burrage]

User Story
As a Distribution Expert and Data Analyst,
I want to add the ability to parse for utm_source and utm_campaign values from a deferred deeplink (e.x. curiousreader://app?language=afrikaans&utm_source=facebook&utm_campaign=120208084211250195),
So that I can receive attribution information from a distribution channel and have it ready to store with the user's event data in a later task card.

Acceptance Criteria
Given that I have a deferred deeplink with language, utm_source, and utm_campaign values,
When I test the deferred deeplink through the Facebook deeplink tester and view the console,
Then I should see the values passed in the AppLinkData field.

Given that I have received the deferred deeplink in the AppLinkData field from Facebook,
When I parse the output,
Then I should have values for language, utm_source, and utm_campaign as separate variables for storage.
