Basic Auth Header Parser

The `basic-auth-parser` package provides a minimalist utility for parsing the `Authorization` HTTP header specifically for Basic Authentication schemes. It extracts the authentication scheme (e.g., 'Basic'), username, and password from a base64-encoded header string. The current stable version is 0.0.2-1, which was last published over four years ago, indicating that the package is no longer actively maintained. Due to its age and lack of updates, it does not support modern JavaScript module systems like ESM out-of-the-box, relying solely on CommonJS. Key differentiators from more actively maintained alternatives like `basic-auth` (from `jshttp`) or `http-auth-utils` include its extremely small footprint and singular focus, but this comes at the cost of modern features, security updates, and broader ecosystem support.
