/**
 * This function will call the callback when the system has very likely woken up from sleep.
 * It will ignore small delays and will only call the callback if the system was disconnected during sleep.
 * @param callback - the function to call when the system wakes up
 * @param isDisconnected - (optional) a function to make sure the connection was lost, to reduce the chance of false positives
 * @returns a function to stop the interval
 * @example
 * ```typescript
 * const stop = onBackFromSleep({
 *  callback: () => {
 *   console.log('Woke up from sleep');
 * },
 * isDisconnected: () => {
 *  return !navigator.onLine;
 * }
 * });
 * ```
