Let's tidy up the imports in __init.py__...

__all__ = [
    # __version__.py
    "__description__",
    "__title__",
    "__version__",

    # _api.py
    "delete",
    "get",
    "head",
    "options",
    "patch",
    "post",
    "put",
    "request",
    "stream",

    # _auth.py
    "Auth",
    "BasicAuth",
    "DigestAuth",
    "NetRCAuth",

    ...
]
