Compatibility with Round 2 SNOVA
-------

While the SNOVA parameter space has been expanded and the recommended parameters have changed, the algorithm itself has not changed between rounds 2 and 3. The Round 2 KAT files can still be created by using appropriate parameters. For example, for the `generic` implementation
```
make clean kat P="-D SNOVA_v=24 -D SNOVA_o=5 -D SNOVA_q=16 -D SNOVA_l=4 -D SNOVA_r=4 -D SNOVA_m1=5 -D SNOVA_alpha=20 -D FIXED_ABQ=0 -D HASH_PK=0 -D ROUND2_T12=1 -D SNOVA_NAME=SNOVA_24_5_4_SHAKE"
```
This will create a response file `PQCsignKAT_SNOVA_24_5_4_SHAKE.rsp`. To check for changes against the Round 2 version:
```
diff PQCsignKAT_SNOVA_24_5_4_SHAKE.rsp $SNOVA_KAT/Round2/PQCsignKAT_SNOVA_24_5_4_SHAKE_SSK.rsp
```
