Approximate magnitude of 2d and 3d vectors

Vec3 Magnitude

These C# implementations of approximate magnitude with no square roots are actually slower than calling a native implementation in Unity, but if this were implemented intelligently in C there's a good chance they would be faster. In any case, they're here because it was a pain to get the magic numbers.

Accurate to within 4.5%.
