/**
 * Creates a buffered asynchronous iterable from an input iterable with a specified time delay between elements.
 *
 * @group Lazy helpers
 * @template T - The type of elements in the input iterable.
 * @param ms - The number of milliseconds to delay between elements.
 * @returns A function that accepts an input iterable and returns a buffered asynchronous iterable with the specified delay.
 *
 * @example
 * ```ts
 * const input = [1, 2, 3];
 * const bufferedIterable = buffer<number>(500)(input);
 *
 * (async () => {
 *   for await (const x of bufferedIterable) {
 *     console.log(x); // Logs 1, 2, 3 with a 500ms delay between each value
 *   }
 * })();
 * ```
