Adding middlewares

[alburkerk]

Following this this discussion : #909

I created a draft PR to enable configuration.

• Middleware are now fully customisable in Tooltip config (no data attribute config for now)
• Relevant floating-ui middlewares are exported from the barrel file to prevent user to create a useless peer dependancy
• Exemple in app.tsx demonstrating a use case

Thanks for the contribution. Everything seems fine at first glance.

I'll do some testing later and also update the docs.
