 * Custom hook that executes a callback function at specified intervals.
 * The first execution happens after `initialDelay`, and subsequent executions
 * happen every `repeatInterval` milliseconds.
 *
 * @param callback - The function to execute at each interval.
 * @param deps - Dependencies for updating the callback function.
 * @param initialDelay - Initial delay before the first execution in milliseconds.
 * @param repeatInterval - Interval between subsequent executions in milliseconds. If not provided it falls back to the initialDelay.
 * @returns An object containing the latest value returned by the callback and the last updated timestamp.
