Renders a Prebid banner into a GPT interstitial slot using the default Prebid Universal Creative

Notes:

• The PUC renders the banner immediately when returned from GAM, despite not being viewable
• pbjs.triggerBilling is being used but no bid adapters seem to be using the onBidBillable event (ref)
• The iframe containing the banner needs to be resized due to the 1x1 size of the PUC
