Feature Request: allow items reordering

[SeriousMonk]

Hi, thank you for this package it's truly amazing!

I would like to suggest a new feature. It would be relly cool if this package could suppport item reorder using drag and drop.
Basically the user should be able to pick up a node of the tree and drag and drop it anywhere else in the tree at the same level.

What I'm suggesting is a behavior similar to this, but adapted to work on a tree structure:

There currently is no package that supports item reordering on more than 2 levels, and I believe this package has the structure to support this freature without any crazy work necessary, since it is already based on ReorderableListView.

I created a fork and started working on this, but my skills and understanding of the structure of this package are insuficcient to complete the task.

This seems like a nice feature to have.
I have had a look at the SliverReoderableList, and it seems that it can be integrated with the AnimatedTreeView. This might take a bit of time to get it right, but it certainly is doable.
Thanks for the suggestion.

If it can be of any use for the implementation of some behaviors, the gif was taken from https://pub.dev/packages/drag_and_drop_lists

I haven't been able to find time to work on this feature due to my current office work load. I will start some work once I am able to find some time. Thanks for your patience :)
