Current behavior

The optimized method get_value_opt for shepard interpolation had a great speed up by #501. However, this method did not support (even before than the #501) arrays of inputs.

New behavior

Inspired by the implementation made in the aforementioned PR, the support for multiple inputs was added in the optimized way, benefiting from the great speed up implemented. Since this also satisfies the requisites for the common get_value method while being faster, it was also updated.
