Hyperbolic tangent kernel.
For any two vectors \( x \), \( y \) and a given scale \( s \) and offset \( t \)
\[ K(x, y) = \tanh(s <x, y> + t) \]

| scale | Scaling factor for <x, y>. |
| offset | Kernel offset. |

Evaluate the hyperbolic tangent kernel.
This evaluation uses Armadillo's dot() function.
| VecTypeA | Type of first vector (should be arma::vec or arma::sp_vec). |
| VecTypeB | Type of second vector (arma::vec / arma::sp_vec). |
| a | First vector. |
| b | Second vector. |
