Kernel radius^2 0.6 -> 0.5, scale 42 -> 105, permute (34x+1)x -> (34x+10)x, per
stegu/webgl-noise 22434e04d7 (fix 21d9fe23d7, scale ff3b5d34ea, permute a3e6d57095).
snoise_grad, fbm_grad, ridged_grad follow. C#, both HLSL copies, design.md and
THIRD-PARTY-NOTICES.md change together. The 2D snoise shares the permute helper, so
its values change too. Golden values are regenerated in the next commit.
