alifestd_add_inner_knuckles_asexual(phylogeny_df: DataFrame, mutate: bool = False) → DataFrame

For all inner nodes, add a subtending unifurcation (“knuckle”).

Input dataframe is not mutated by this operation unless mutate set True. If mutate set True, operation does not occur in place; still use return value to get transformed phylogeny dataframe.
