Pre-generate sample data cache for rate_aware_gen.py debugging.
Generates and saves cache files for 2-user and 3-user configurations,
so subsequent runs of rate_aware_gen.py can load instantly instead of
regenerating data each time.
Usage:
python pregen_cache.py # default: small scale, 15000 samples
python pregen_cache.py --n-samples 2000 # smaller debug set
python pregen_cache.py --scale small --n-samples 15000
