    Split chromosomes into chromosome arms.

    Parameters
    ----------
    chromsizes : pandas.Dataframe or dict-like
        If dict or pandas.Series, a map from chromosomes to lengths in bp.
        If pandas.Dataframe, a dataframe with columns defined by cols_chroms.
        If cols_chroms is a triplet (e.g. 'chrom','start','end'), then
        values in chromsizes[cols_chroms[1]].values must all be zero.
