add "use client" to HydrationProvider

[cassus]

Hi @traviswimer,

Thanks for this great tool!

I'm using React 18 with server components in NextJS. I get the following error

Server Error
Error: createContext only works in Client Components. Add the "use client" directive at the top of the file to use it. Read more: https://nextjs.org/docs/messages/context-in-server-component

Would you add "use client" to HydrationProvider?

[traviswimer]

Yes, although I think use client will be necessary in several other files as well, since useEffect() is fundamental to how it works.

I think the library in general should work fine with server components once that's added, although there may be something I'm overlooking.

You can make a PR if you'd like, otherwise I'll try to get this added soon.

@cassus Just published this in v2.1.0 if you want to try it out.

Also added a small section to the README: https://github.com/traviswimer/react-hydration-provider/tree/v2.1.0#usage-with-server-components
