This is basically the change -- use build rather than new_exec which I think is more consistent with the style of code in the rest of this crate (and the Rust builder style in general)

Previously calling new_exec always cloned. Now it is only cloned when necessary

| Arc::new(DataSourceExec::new(Arc::new(self.clone()))) | ||
| /// Returns a new [`DataSourceExec`] to scan the files specified by this config | ||
