Setting an Ad-id

If you would like the mobile user's advertising identifier (idfa) to be present in remote analytics, you may pass in the user's advertising identifier after enabling remote analytics. For example:

- (void)engineDidStartWithInstance:(FactualEngine *)engine {
  NSLog(@"Engine started.");
  
  [engine enableRemoteAnalytics];
  [engine setAdId:@"user-ad-id"];
  ...
