…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.

> Iceberg hopes to implement the column index filter based on Iceberg's own
> expressions, we would like to be able to use some of the methods in Parquet
> repo, for example: methods in `RowRanges` and `IndexIterator`, however these
> are currently not public. Currently we can only rely on reflection to use
> them.
