💡 Add detection of unused JSX (React) props

Suggest an idea for this project

Hi, I noticed that this project did not have support for detecting unused react properties yet. I figured I could help in implementing it since I've done so adjacent work in my past.

Since I mainly just wanted to check "is this possible at all" before opening an issue I've gone ahead and already implemented it in this PR. I'm pretty sure it's not fully complete though, and you may not fully agree with the approach. So i'm opening this issue to allow for some broader discussion on the topic and to ask you if you maybe had an approach in mind already. Of course my implementation can be tweaked (or discarded and used as inspiration) if so needed.
