A backend and API service for serving the Voyager application.
It is a FastAPI that can be run with gunicorn in production. A data directory, where voyage data in the correct format can be found, needs to be provided in the config file.
Instead of gunicorn, the app can also be run locally with fastapi run if the cli-package fastapi[standard] is installed additionally.
The voyager base module is currently found in another repository and needs revision.
