This object represents an allowed size (i.e., height and width combination) or Flex Ad parameters
for a banner impression. These are typically used in an array where multiple sizes are permitted.
It is recommended that either the w/h pair or the wratio/hratio/wmin set (i.e., for Flex Ads) be
specified.
