Which issue does this PR close?

Closes #3476.

Rationale for this change

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).

What changes are included in this PR?

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.

Are there any user-facing changes?

New CLI: parquet-rewrite.
