Title: Support for calling RequestBannerAd with a null 'extras' parameter

The Unity iOS plugin would fail to request any ads unless you passed in a valid JSON string for the 'extras' parameter of RequestBannerAd. This is different than the Android plugin, which has two version of that method: one with extras and one without. This change modifies the iOS API to accept null/nil for 'extras'.
