/**
 * Generates sliding views of the given array of the given size and returns a new
 * array containing all of them.
 *
 * If step is set, each window will start that many elements after the last
 * window's start. (Default: 1)
 *
 * If partial is set, windows will be generated for the last elements of the
 * collection, resulting in some undefined values if size is greater than 1.
 * (Default: false)
 *
 * Example:
 *
 * ```ts
 * import { slidingWindows } from "https://deno.land/std@$STD_VERSION/collections/mod.ts";
 * import { assertEquals } from "https://deno.land/std@$STD_VERSION/testing/asserts.ts";
 * const numbers = [1, 2, 3, 4, 5];
 *
 * const windows = slidingWindows(numbers, 3);
 * assertEquals(windows, [
 *   [1, 2, 3],
 *   [2, 3, 4],
 *   [3, 4, 5],
 * ]);
 *
 * const windowsWithStep = slidingWindows(numbers, 3, { step: 2 });
 * assertEquals(windowsWithStep, [
 *   [1, 2, 3],
 *   [3, 4, 5],
 * ]);
 *
 * const windowsWithPartial = slidingWindows(numbers, 3, { partial: true });
 * assertEquals(windowsWithPartial, [
 *   [1, 2, 3],
 *   [2, 3, 4],
 *   [3, 4, 5],
 *   [4, 5],
 *   [5],
 * ]);
