[Feature] Nested Overlays

# **Feature Request**

## **Is your feature request related to a problem? Please describe.**

Cloudinary gives you the ability to "nest" overlays in a way that allows the elements to flow in a natural way.

Example would be based on dynamic text positioning, the nested overlay would dynamically be placed after it if using relative positioning.

## **Describe the solution you'd like**

Not quite sure, thinking maybe along the lines of:

```
overlays={[
{
...
children: [{ ...overlays }]
]}
```

Where the children would be instances of overlays, so the overlays plugin would just recursively parse the children and down

## **Describe alternatives you've considered**

maybe `childOverlays` instead?
