> For now, the only way to encode column with dict-encoding is to set {{auto_dict_encode = True}} at {{arrow::csv}}{{::}}{{ConvertOptions}}
> However, users should have the ability to specify column type as dict explicitly via {{column_types}} parameter. (Currently it is raising an exception that dict type is not supported)
