Orphaned python-aiohttp-cors

Hello, I've maintained python-aiohttp-cors because python-black required it, but it no longer does, so I've just orphaned it. The package is now only required by gns3-server. The package builds, installs, builds with Python 3.11 (we have just pushed a fix). However, it appears dead upstream. Consider dropping the dependency instead of taking the package. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok
