Situation:
- import wizard is creating CsvParserSettings instance with all selected columns definition
- CsvParserSettings being handed over to Task to run CsvParser in new Thread
- need to set there conversions per selected column
Question:
- is there a way to get from CsvParserSettings the selected indexes
Note: method public FieldSet<Integer> selectIndexes(Integer... fieldIndexes) is used to define the selection rather to read it back
Alternative solution: provide also Array of column indexes
