This version adds support for the new Engage API introduced in the Analytics SDK and fixes a few bugs.
Instead of calling showAd() or showRewardedAd() (or the variants which take a decision point as an argument) in order to show an ad, instances of the InterstitialAd or RewardedAd class need to be created and shown.
Either class can be instantiated through static create() methods which take a varying amount of arguments, and shown by calling show(). If an ad is created from an Engagement instance then the created instance needs to be null checked, as the decision point may not have been setup for display an ad.
