 /**
 * Applies a binary callback accepting and returning unsigned 8-bit integers to unsigned 8-bit integer strided input arrays, casts the callback's unsigned 8-bit integer return value to an unsigned 16-bit integer, and assigns results to elements in an unsigned 16-bit integer strided output array.
 *
 * @param arrays   array whose first two elements are pointers to strided input arrays and whose last element is a pointer to a strided output array
 * @param shape    array whose only element is the number of elements over which to iterate
 * @param strides  array containing strides (in bytes) for each strided array
 * @param fcn      callback
 *
 * @example
 * #include "stdlib/strided/base/binary/bb_t.h"
 * #include <stdint.h>
 *
 * // Create underlying byte arrays:
 * uint8_t x[] = { 0, 0, 0 };
 * uint8_t y[] = { 0, 0, 0 };
 * uint8_t out[] = { 0, 0, 0, 0, 0, 0 };
 *
 * // Define a pointer to an array containing pointers to strided arrays:
 * uint8_t *arrays[] = { x, y, out };
 *
 * // Define the strides:
 * int64_t strides[] = { 1, 1, 2 }; // 1 byte per uint8, 2 bytes per uint16
 *
 * // Define the number of elements over which to iterate:
 * int64_t shape[] = { 3 };
 *
 * // Define a callback:
 * uint8_t add( uint8_t x, uint8_t y ) {
 *     return x + y;
 * }
 *
 * // Apply the callback:
 * stdlib_strided_bb_t( arrays, shape, strides, (void *)add );
