Jextract currently has two output modes: class files, and source files. The intended use is to use the source files, add them to your project, and then compile along with the rest of the source files in your project. However, source mode is not the default at the moment.

We should make the source mode the default, and then just drop the class file output mode. We don't compile the classes in any special way, so a client can always compile the class file themselves.
