Polkadot Middleware

The `polkadot-middleware` package provides a familiar middleware pattern for the `polkadot` HTTP server, streamlining request handler composition. Currently at version 1.0.1, it offers a functional alternative to manual function nesting, simplifying the development of server-side logic. This library addresses the current lack of a native pipeline operator in JavaScript, allowing developers to chain asynchronous request/response functions linearly. It serves a specific niche for users of the lightweight `polkadot` server who desire an Express.js-like middleware experience without significant overhead, focusing on readability and maintainability for simple API servers.
