Handle improperly build image files gracefully
Images build improperly (by simply concatenating separate images) were accepted, but anything after the first end-of-file record *silently* ignored. Now emit warning for intel and motorola images upon non-whitespace after first end-of-file record but continue reading anyway. ST ships some images broken that way in their CubeMX packages ...
