We implement this for first and second order tensors in gonum.org/v1/gonum/mat[1], which you are welcome to borrow from to extend to third order. Our slice operation[2] is in principle non- allocating (though we do allocate a container for generality - a non- allocating version would simply not return the pointer type for the Dense).
