Description
Part of #629.
TPC-DS benchmark preparation currently hard-limits the scale factor to SF1. Allow callers to select supported scale factors and generate the matching Parquet dataset layout under testdata/tpcds/sf<scale-factor>.
Scope:
- Remove the SF1-only restriction from the TPC-DS preparation and generation path.
- Keep the generated layout compatible with
./benchmarks/run.sh --dataset tpcds/sf<scale-factor>.

Research direction
Read issue #629 for the detailed wiring guidance, then locate the TPC-DS preparation and generation path that currently restricts scale factors to SF1. Verify that supported factors produce datasets under testdata/tpcds/sf and remain compatible with ./benchmarks/run.sh --dataset tpcds/sf.
