Summary
Ward Beullens found a practical key-recovery attack against Rainbow. The level I parametersets are removed from liboqs starting from version `0.7.2`. Find the scientific details in [Breaking Rainbow Takes a Weekend on a Laptop](https://eprint.iacr.org/2022/214). This means all the `oqs::sig::Algorithm::RainbowI*` variants are insecure.
