### Reason for this PR This PR addresses the feature request in #397 and improves upon PR:#697 by automatically selecting `Scanner` or `FileReader`. Using `Scanner` when predicate pushdown is available, and falling back to `FileReader` when it is not. ### What changes are included in this PR? If predicate pushdown is available, the selected columns are pushed down into `FilterOptions.columns`. Otherwise, the `FileReader` is used to read only the selected columns. ### Are these changes tested? yes, as in #697 ### Are there any user-facing changes? yes, as in #697 -- This is an automated message from the Apache Git Service.
