Consider using an express alternative

[43081j]

The project currently uses express, but doesn't really need the feature set it provides and only leans on the fact that it can support middleware.

We could quite easily move to something like polka or h3.

Both support middleware, are faster, and much smaller than express.

All of the middleware in this project seems to already rely on the built in response/request rather than the express-specific one, too. So we're not locked into a vendor here.

Let me know if you're open to this and i can open a PR or share the issue to see if anyone else is interested in doing so.
