Write asyncTimeout(fn, delay) function that takes an async function and timeout duration in milliseconds.

Requirements:

• Returns a new function with time limit
• If function completes in time - returns its result
• If exceeds timeout - rejects with "Timeout exceeded" error
• Must pass all arguments to the original function

Example:

const slowFn = async (n) => {
  await sleep(1000);
  return n * 2;
};

const fastFn = asyncTimeout(slowFn, 500);
await fastFn(5); // Error: Timeout exceeded
