The BLS12-381 driver's
NewRandomZrcallsfr.Element.SetRandom(), which ignores therngargument and always reads from crypto/rand. So unlike other drivers, it silently drops the caller's reader. This breaks reproducible (seeded) tests.The PR changes this to sample with
rand.Int(rng, &c.Modulus)like the common base driver does, and adds a test that checks the same seed gives the same scalar on every curve.
