Add 'mask' command to parquet-tools/parquet-cli

Some personal data columns need to be masked instead of being pruned(Parquet-1791). We need a tool to replace the raw data columns with masked value. The masked value could be hash, null, redact etc.  For the unchanged columns, they should be moved as a whole like 'merge', 'prune' command in Parquet-tools. 

Implementing this feature in file format is 10X faster than doing it by rewriting the table data in the query engine.

#### Subtasks:

- [ ] [Add hash functionality ](https://github.com/apache/parquet-java/issues/1601)

_{**Note**: *This issue was originally created as [PARQUET-1792](https://issues.apache.org/jira/browse/PARQUET-1792). Please see the [migration documentation](https://issues.apache.org/jira/browse/PARQUET-2502) for further details.*}

Start in the parquet-tools/parquet-cli command implementations, using the existing merge and prune commands as references. Review the linked null and hash subtasks before deciding how masking should support hash, null, and redact values. Done means a mask command replaces selected raw columns while moving unchanged columns as a whole.
