How to use the snps.io.Writer function in snps

----------
        filename : str or buffer
            filename for file to save or buffer to write to
        vcf : bool
            flag to save file as VCF

        Returns
        -------
        str
            path to file in output directory if SNPs were saved, else empty str
        """
