Feature Request: Highlighting based on bounding box coordinates

[richard-greenbaum67]

Hello,

I see that the useHighlightContext hook already makes it easy to add page highlights based on keywords and regex. Would it be possible to add a highlighting option that lets the programmer specify the bounding box rectangle to highlight on a given page, similar to how it is done in the react-pdf-viewer highlight plugin? This would be really helpful for my project.

Thanks for putting together an awesome component!
