static update_gene_info(df: pandas.DataFrame)

Updates gene info in 2 steps: - First, columns are added if they were not present. This is done by going from the highest level of information (alleles)

towards the lowest level of information (subgroups) by stripping away suffixes. If gene and subgroup columns were already present, suffixes are still stripped away just in case.

• Next, if there are None values present, the highest possible level of information is copied in from the lower level information fields. This is done by moving from subgroups towards alleles. So if for one particular receptor only the subgroup was present, the subgroup will be copied into the genes and alleles column.
