   …implement page skipping.
   
   Issue: [PARQUET-2252](https://issues.apache.org/jira/browse/PARQUET-2252)
   
   This PR makes some methods required to implement column index filter public 
to allow Iceberg build its own column index filtering.  Since Iceberg is going 
to calculate `RowRanges` itself, this also adds a public method in 
`ParquetFileReader` that allows users to pass in `RowRanges` to read filtered 
row group. Use of these changes can refer to this 
[PR](https://github.com/apache/iceberg/pull/6967), currently it uses reflection 
as a workaround.
