Return the stereo parent of a given molecule.

        The stereo parent has all stereochemistry information removed from tetrahedral centers and double bonds.

        :param mol: The input molecule.
        :type mol: rdkit.Chem.rdchem.Mol
        :param bool skip_standardize: Set to True if mol has already been standardized.
        :returns: The stereo parent molecule.
        :rtype: rdkit.Chem.rdchem.Mol
