Expose row index to Node renderer

[joshhunt]

I'm trying to give my rows alternate "striped" colors. Using :nth-child(2n + 1) is not great because you get a weird effect as you scroll as items are added and removed from the div.

It would be handy if react-vtree exposed the current row index to the Node renderer. It looks like this is already available internally https://github.com/Lodin/react-vtree/blob/f4d9cd4/src/Tree.tsx#L187

this would also be helpful for debugging purposes

Hi @joshhunt ,
Have you found a solution on how to implement it without changing the source code of the package?

No - I changed the code 😌
