Create test directories for modules 16-20

- Add tests/16_quantization with run_all_tests.py and integration test
- Add tests/17_compression with run_all_tests.py and integration test
- Add tests/18_acceleration with run_all_tests.py and integration test
- Add tests/19_benchmarking with run_all_tests.py and integration test
- Add tests/20_capstone with run_all_tests.py and integration test
- All test files marked as pending implementation with TODO markers
- Completes test directory structure for all 20 modules
