    The pinning file can be used to pin paths in USD to specific filepaths,

    dynamic URIs (like "get me latest version") to be pinned to the version
    at the time of the generation.

    Arguments:
        entry_usd: The USD filepath to generate the pinning file for.
        root_info: The project roots for the site the pinning should resolve
          to. These can be obtained via e.g. the AYON REST API get
          `/api/projects/{project_name}/siteRoots".
        pinning_file_path: The destination path to write the pinning file to.
