generate-copyright: Now generates a library file too.
We only run reuse once, so the output has to be filtered to find only the files that are relevant to the library tree. Outputs COPYRIGHT.html and COPYRIGHT-library.html. The license-metadata.json file is also now in the tree. We need a CI tool to check that it's correct.
