 * Sets the value at path of object. If a portion of path doesn't exist, it's created.
 * Arrays are created for missing index properties while objects are created for all
 * other missing properties.

 * @param object - The object to modify
 * @param path - The path of the property to set
 * @param value - The value to set
 * @returns The modified object
 *
 * @example
 * ```ts
 * const object = { 'a': [{ 'b': { 'c': 3 } }] };
 *
 * set(object, 'a[0].b.c', 4);
 * // => { 'a': [{ 'b': { 'c': 4 } }] }
 *
 * set(object, ['x', '0', 'y', 'z'], 5);
 * // => { 'a': [{ 'b': { 'c': 4 } }], 'x': [{ 'y': { 'z': 5 } }] }
