handle Sailthru Link
If you're using Marigold email with universal links, your application will open with an encoded Marigold link url. This method will decode the link URL and return its canonical location (ie https://link.sailthru.com/blahblah will redirect to https://www.sailthru.com/careers/list/, the link's canonical location), as well as making sure that the clickthrough metrics for this link are correctly attributed in the Marigold platform. This method should be called from your receiving activity's onStart()
method, and handle the starting intent's link data
Return
the destination that the Marigold link points to
Parameters

Throws
when the URI given isn't a Marigold link
