Extractor can now use a Controller to define voxel type and threshold
...
In future, it will also be used to extract pre-computed gradients and
intersection points.

Explicitly cast these to floats

Require that the voxel is a signed type
...
This means that a static_cast<float> is no longer needed to calculate the
gradient. A static_assert provides user feedback.
The next step here would be to use a MarchingCubesController-type solution
to define the density value from a voxel. This way, also the gradient can
be stored.

Performance is up from 10 times slower than MC to only 3 times.
About a third of that time is spent calculating gradients.
