JCodec: FrameGrab8Bit.class not included in JAR download - how do I add it?

Question

I just downloaded the latest version of JCodec: JCodec-0.1.9. However, I noticed the manifest doesn't include FrameGrab8Bit.class. As Picture has been deprecated and supplanted by Picture8Bit it would be nice, and almost necessary, to have access to the methods of FrameGrab8Bit. As the file is not included in the JAR, I was wondering how I could easily add the mising file to the JAR (I'm using Windows 10), or if there is another way I could add the file to the project.
