Show column names instead of column indices in query plans

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

I am comparing query plans between Spark and DataFusion

Spark shows:

FileScan parquet [ss_sold_time_sk#215,ss_hdemo_sk#219,ss_store_sk#221] ...

DataFusion shows:

TableScan: store_sales projection=Some([1, 5, 7])

I think we should show column names rather than numeric indices.
