get_lib on Windows does not work in Python interactive

[nojaf]

Steps to reproduce:

• Open an interactive Python session on Windows

import mlflow_go.lib
mlflow_go.lib.get_lib()

This will not work on Windows, workaround would be to run python -m mlflow_go.lib . . and set the MLFLOW_GO_LIBRARY_PATH environment variable to ".".

The key problem here is that the tmpdir in

def _get_lib():
    # check if the library exists and load it
    path = pathlib.Path(
        os.environ.get("MLFLOW_GO_LIBRARY_PATH", pathlib.Path(__file__).parent.as_posix())
    ).joinpath(_get_lib_name()).absolute()
    if path.is_file():
        return _load_lib(path)

    logging.getLogger(__name__).warn("Go library not found, building it now")

    # build the library in a temporary directory and load it
    with tempfile.TemporaryDirectory() as tmpdir:
        return _load_lib(
            build_lib(
                pathlib.Path(__file__).parent.parent,
                pathlib.Path(tmpdir),
            )
        )

is being removed after it was invoked. In Windows you cannot delete a file you are executing, this is allowed on unix.
