   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   `ArrowReader::get_schema_by_columns` has a `leaf_columns` argument that switches between selecting between the indexes of leaf columns, and the indexes of the root schema element.
   
   This is helpful because not only does it highlight to the end-user that there is a distinction, but depending on the use-case the user might want either behaviour.
   
   **Describe the solution you'd like**
   
   Add a `leaf_columns` field to `ArrowReader::get_record_reader_by_columns`
   
   **Describe alternatives you've considered**
   
   We could not do this
   
   **Additional context**
