/**
* Creates a debounced function that delays invoking `func` until after `delay` milliseconds have elapsed since the last time the debounced function was invoked.
* @param func The function to debounce.
* @param delay The number of milliseconds to delay.
* @param options Optional configuration options.
* @param options.leading Whether to call the function on the leading edge of the timeout.
* @returns A debounced function that can be called multiple times, but only invokes `func` once per `delay` milliseconds.
