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

    Implementation of a custom transfer agent for the transfer type "multipart"
    for git-lfs. This lets users upload large files >5GB 🔥. Spec for LFS custom
    transfer agent is:
    https://github.com/git-lfs/git-lfs/blob/master/docs/custom-transfers.md

    This introduces two commands to the CLI:

    1. $ hf lfs-enable-largefiles

    This should be executed once for each model repo that contains a model file
    >5GB. It's documented in the error message you get if you just try to git
    push a 5GB file without having enabled it before.

    2. $ hf lfs-multipart-upload

    This command is called by lfs directly and is not meant to be called by the
    user.
