Express Smart Authentication Middleware

This package, `smart-auth-middleware`, is an Express.js middleware designed for authenticating incoming requests by validating JSON Web Tokens (JWTs) against an external Identity Service (IDS). It integrates with `jwks-rsa` for fetching JSON Web Key Sets and `express-jwt` for the core JWT verification process. Currently at version 0.21.0, it is in active development, implying that breaking changes might occur more frequently between minor versions as it approaches a stable 1.0 release. The middleware provides a lifecycle with `authPreCheck` for initial validation, `jwtVerify` for token verification and setting user information on `req.user`, and `authPostCheck` to ensure verification success. Its key differentiators include built-in support for JWKS endpoints and configurable options for issuer, audience, and ignored paths, streamlining JWT-based authentication in Express applications.
