Simple CORS Middleware for Micro

micro-cors is a straightforward middleware designed to enable Cross-Origin Resource Sharing (CORS) for applications built with `micro`, a minimalist asynchronous HTTP microservices framework. The package's current stable version is `0.1.1`, which was last published approximately seven years ago. While `1.0.0-alpha` versions were released around five years ago, indicating a past attempt at a major update, development appears to have stalled in alpha, leaving the `0.x` branch as the de facto stable release. It maintains a slow release cadence, essentially being in a maintenance mode. Its key differentiator is its small footprint and specific integration with the `micro` ecosystem, aiming for minimal configuration to handle CORS headers.
