any plan to support parquet?

### Describe the enhancement requested

I saw arrow-cpp and arrow-rs both support parquet format. any plan to support parquet in swift?

Start with the arrow-cpp and arrow-rs Parquet implementations as comparison points, then locate the corresponding support surface in arrow-swift. No Swift file or test entry point is named in the issue. Done should be a decided implementation scope for Parquet support in Swift, with tests covering the supported behavior.
