How to use the jsii._embedded.jsii function in jsii

# temporary directory and extract our resources to there, but we don't want to

        # we will check what loader the embedded package used, if it's a
        # SourceFileLoader then we'll assume it's going to be on the filesystem and
        # just use importlib.resources.path.
