ConvertResults: Drop empty columns in output CSVs
Request Summary
Currently, all output columns will be written to the CSV files, regardless of whether they are empty or not. Add a boolean option to switch between keeping / suppressing empty columns. Default shall be to keep the columns. If columns are suppressed, do not add their metadata to the output metadata file.
Use case
Empty columns clutter files. However, some workflows might need the same column structure, regardless if they are empty. Thus, add possibility to remove the columns.
