The first can be checked in a unit test that matches a byte. The second one is similar to examples in the GIF schema <https://github.com/DFDLSchemas/GIF/blob/master/src/main/resources/com/mitre/gif/sch/GIF.sch#L74-L76>. That schema can be added in the PR unit tests, to go along with the BMP and JPEG.
