Title: Allow dataURL strings to be added directly

Based on the code and documentation, it looks like Whammy is suppose to be able to support directly adding dataURL in the form of image/webp. However the add function tries to use the "in" operator to check for the existence of a property on the frame variable, which is not useable in strings.
