Implementation of a custom transfer agent for the transfer type "multipart" for
git-lfs.

Inspired by:
github.com/cbartz/git-lfs-swift-transfer-agent/blob/master/git_lfs_swift_transfer.py

Spec is: github.com/git-lfs/git-lfs/blob/master/docs/custom-transfers.md


To launch debugger while developing:

``` [lfs "customtransfer.multipart"]
path = /path/to/huggingface_hub/.env/bin/python args = -m debugpy --listen 5678
--wait-for-client
/path/to/huggingface_hub/src/huggingface_hub/commands/huggingface_cli.py

    This command sets up git-lfs to use the custom multipart transfer agent
    which enables efficient uploading of large files in chunks.
