Expose pixel to index function

[nick-keller]

First of all, congratulations on this great lib, very easy to work with.

What is the feature request?

I'd like the Virtualizer to expose a method that would allow me to pass a value in pixels, and get back a VirtualItem.

The story

I am the maintainer of react-datasheet-grid which uses this lib to virtualize a 2D grid. I need to convert user clicks to cell coordinates.

• I cannot use onClick or other event listener on cells since the user might drag the mouse outside of the grid
• Not trivial to copmute with dynamic item size

Conclusion

I ended up re-writing the core logic of this library just for this, and even considering re-implementing virtualization myself... :/
I feel like this feature sould be trivial to implement since the logic is already there under the hood.

Let me know what you tink!

Hi @nick-keller,

thanks 💪

I think that's a valid request, right now we expose getOffsetForIndex, getOffsetForAlignment adding getVirtualItemForOffset sound good, checkout the #505

Damn, congrats on the delivery, impressive work ;p
