spatial/r3: use lightweight matrix for rotations
...
This implements mat.Matrix and mat.RawMatrixer to gain the fast path for
matrix multiplication but does not have any of the machinery for resizing.

spatial/r3: harmonize Vec API with num/quat.Number
...
Migration to the new API can be achieved with this rsc.io/rf script:
```
rf ex {
import "gonum.org/v1/gonum/spatial/r3";
var p,q r3.Vec;
var f float64;
p.Add(q) -> r3.Add(p, q);
p.Sub(q) -> r3.Sub(p, q);
p.Scale(f) -> r3.Scale(f, p);
p.Dot(q) -> r3.Dot(p, q);
p.Cross(q) -> r3.Cross(p, q);
p.Rotate(f, q) -> r3.Rotate(p, f, q);
}
```
