Add binder link

[MarcSkovMadsen]

Hi

I am a contributor to HoloViz Panel and wanted to quickly check out this repo to understand how it uses Panel.

It seems I have to do a local installation if I want to play around with this. It would help me and probably others if we could quickly try out this project on Binder instead of having to install and clean up on our laptops.

Please add binder link.

For inspiration checkout my binder configuration here https://github.com/MarcSkovMadsen/panel-chemistry/tree/main/binder and how I use it in my README.md file https://github.com/MarcSkovMadsen/panel-chemistry
