Reafactor ui-modal

[BataevDaniil]

1. move hide, show, isVisible in other atom
2. add +-decorator for animating modal
3. add queue for controlle many modal
4. add example with controlle modal and data for modal

The main issue is internal realisation and it reliability. It should be written in FSM style. Btw, I already thinking around a helper for FSM describing.

Do you really want to have atom controlling component to be outside of the component? That breaks encapsulation I would say

If this logic is more than 50 LoC - defenetly yes! react-aria and ariakit show us the this pattern is good and powerful, it give us more flexibility.
