[Feature] useMutationObserver

[Dchole]

I have a useMutationObserver hook that handles the MutationObserver API in my react code.

The MutationObserver API is very similar to the IntersectionObserver API. It provides the ability to listen to changes made in the DOM tree. I'll love to make a PR and have it included in the library

Awesome hook! Yes, it's more than welcome 🙏
You could use the npm run plop script to create the hook boilerplate.
Thanks!
