Order of multiple notificatiions

[lexoyo]

Hi
Thx for this nice simple library
In the case of "Queued Notifications" the order is inverted:

  const show = notify.createShowQueue();
  // ...
      console.log(show(operation.title + '1'));
      console.log(show(operation.title + '2'));
      console.log(show(operation.title + '3'));
      console.log(show(operation.title + '4'));

This will show toasts in this order:
1- "My operation1"
2- "My operation4"
3- "My operation3"
4- "My operation2"

Also a few notes I have:

• the return value of the show method is not documented
• the fact that there is only 1 toast at a time should be documented or an option (max number of toasts in createShowQueue maybe?)
