feat/objbench:

### Add verbose logging and file deletion in `objbench.rs`

 - **Verbose Logging**: Introduced a `--verbose` flag in `Command` to enable detailed logging using `common_telemetry::init_default_ut_logging()`.
 - **File Deletion**: Implemented automatic deletion of the destination file after processing in `Command::run()`.

 ### Update tests in `parquet.rs`

 - Removed unused parameters in test functions to streamline the code.
