 * Debounce dispatching a function.

 * By default the function will wait [timeout] amount of time before
 * dispatching the function. If the [leading] arg is set to `true`, then
 * this logic will change to dispatching on the first request and ignoring
 * all subsequent requests in the [timeout] period proceeding.
 *
 * @param fn Function to be called
 * @param timeout Number of milliseconds
 * @param leading If the dispatch should fire on the leading request. Default is last recieved request.
 * @returns Dispatch function
 * @see https://www.freecodecamp.org/news/javascript-debounce-example/
 * @example
 *  const fn = useDebouncedFn(() => {}, 1000);
 *  fn();
 *  fn();
 *  fn(); <-- only this one will run
 * @example
 *  const fn = useDebouncedFn(() => {}, 1000, true);
