DetectorModel: allow overriding isWithinMatrix for local coordinates

         * @brief Returns if a position is within the grid of pixels defined for the device

         * @param position Position in local coordinates of the detector model

         * @return True if position within the pixel grid, false otherwise

         *

         * @note This method is virtual and can be implemented by detector models for faster calculations
