Release v1.1.0

- Implement high-level `download_model` API that wrap it with `fire-cli` 🔥 Note that desired quants can now be passed with `-q` and branch with `-b` versus the previous positional arguments.

- Turned `get_filenames` into a generator to support downloading multiple files with one call

- Added a fallback to `get_redirect_header` to return original URL in case there's no redirect (supports downloading non-LFS files like *.json and tokenizer models)
