Changelog: 🚀

### Added
 
* New `handleScroll` option allows customizing scrolling behavior.
 
### Changed
 
* Animation logic is separated from scroll calculation logic. This allows skip
  importing animation dependencies and reduces bundle sizes when you don't need
  the built in animation feature.

### What this means

Take control over how the target is scrolled into view. This function is called
for each parent node that need scrolling. `scrollLeft` and `scrollTop` are
destination coordinates. The from coordinates you'll have to get yourself if you
want to animate the transition using a different library.
 
When using this option you likely don't need the built in animation feature. To
cut down on filesize you can do the following adjustment if you are using a
recent version of webpack or rollbar (and use ES6 imports):
 
```diff
-import scrollIntoViewIfNeeded from 'scroll-into-view-if-needed'
+import maybeScrollIntoView from 'scroll-into-view-if-needed/dist/calculate'
 
-scrollIntoViewIfNeeded(node)
+maybeScrollIntoView(node, {handleScroll: (parent, {scrollLeft, scrollTop}, config) => {
+  // The following is actually the default implementation
+  // if this is all you need you can skip passing this option
+  parent.scrollLeft = scrollLeft
+  parent.scrollTop = scrollTop
+}})
```
