An example use case is a Parquet file where we select different sets of columns and assign each set to a different Mapper. Right now, Pangool overrides the input assignment for the same Path, silently keeping only the last one. A small change is needed for Pangool to be able to delegate to multiple mappers and input formats for the same Path.
