Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Sometimes I wonder what different settings (compression, row group size, page size, ...) do to a parquet file (in terms of size, number of row groups / pages, performance).

Describe the solution you'd like
Have a CLI that takes a parquet file and writes it again w/ different settings. The resulting file can then be inspected by our other CLI tools like parquet-layout.

Describe alternatives you've considered
Always require user code to perform these kind of experiments.
