Benchmark

The benchmark doesn't represent a real world usage of the framework, but it's a closer approximation.

It is running a simple web server that renders some React tree and responds with a stringified HTML. Consists of 1) node + express, 2) bun and 3) dream with server-reason-react.

The application uses the same React tree in all 3 cases, so the differences are:

• runtime
• ReactDOM's implementation
• server framework (if any)

It's based on 384cd79c73be5baddf281b9a089bbf843e1b990d and not what's currently on main.
