> Currently, our {{util::pad_image}} function performs zero-padding, which is
> correct for operations such as convolution. In some cases, such as max
> pooling, it is necessary to pad with a different value such as negative
> infinity. Therefore, we should extend our {{util::pad_image}} function to
> accept a {{pad_value}} parameter with a noted typical value of 0.
