As a user, I want a deck URL endpoint that returns a plain deck list

Example:
https://moxfield.com/decks/<deck hash>
https://moxfield.com/decks/<deck hash>/raw

A new /raw endpoint could return the plain deck list so it is ready to be used with LLMs, without needing to manually download the deck list and paste it into an LLM chat. This is similar to the functionality available on GitHub and GitLab for accessing raw versions of specific files.
