[feature] Express.js Middleware Wrapper

[OpenReplicant]

I just decided to hack together a middleware wrapper (with the help of Claude Sonnet via a test-driven development method, and the docs provided) to make use of potentially any Express.js middleware in Hyperexpress. I learned quite a bit about the differences between the two servers and the request object, and this iteration passed all the tests that had failed to use middleware correctly, still I'd love it if anyone in the know could look it over or test it themselves.
