Generate a prefix for raw downloads — radicle-explorer

GitHub and GitLab will prefix archive payloads with the name of the repo and the refspec. This patch naively applies a prefix in similar fashion.

The refspec might contain filesystem path separators, like a forward slash (/). GitHub and GitLab replace that with a hyphen (-). This patch applies that same replacement.
