Description
**Feature request**
It would be really nice if, when a user mis-specified a column name in `read_parquet(..., columns=[...])`, the error message would include the list of all (nested or not) columns. I believe it would also help with `lsdb.open_catalog(..., columns=[...])`. Right now, it raises a `KeyError: "['non-existing-column'] not in index"` from pandas.
