Add from to bounds coordinates value

[PuruVJ]

When you provide this object to bounds

{
  top: 0,
  bottom: 20,
  left: 30,
  right: 40
}

This is fixed to window. I am gonna provide a new from property to which you specify a selector or pass an element to it. Then the bounds will be calculated wrt to that element.

Example:

{
  from: '.main-el'
  top: 20
}

// OR

```ts
{
  from: document.querySelector('.main-el')
  top: 20
}
