Feature Request: Cody Adapter

[KarlEricsson]

Thanks for a great plugin! I would love a Cody adapter added if possible. Especially now since sg.nvim is abandoned. It think it should be technically possible with this. Hopefully it's not too much work :)

Would welcome a PR and corresponding tests for it. I've written a whole guide on how to do it here and someone from the community added an adapter last week
