by running something like chooseFilter("/p/projects/remind/users/oliverr/data/NGFS4_IAM_data_S1.xlsx"), you get prompts which data you want to select, which will be returned as a quitte object.
the script identifies automatically if there is only a single option (for example: all data has model = REMIND) and then does not ask which model you want
by using the keep list, you can add parts that are never lost. Will need that in piamInterfaces::plotIntercomparison where you will ever want to keep the World data for plotting.
