* optimize `test_ct_intlog2` while still covering all 128 bit positions * refactor whirlpool to reduce code bloat replaced the fully unrolled round loop with a runtime loop, reducing instruction count by 80k in `process_block` and yielding aprox 30% performance boost due to improved cache locality. * use compile-time arrays for `test_ct_intlog2`
