Pykite

**Description:**

1. PyKite now supports middleware for customizing request and response processing.
2. Middleware can be used for tasks like authentication, authorization, logging, caching, and more.
3. A base BaseMiddleware class is provided as a starting point for creating custom middleware.

**Usage:**

1. Create a custom middleware class that extends BaseMiddleware.
2. Implement the process_request and process_response methods to define your middleware's logic.
3. Register the middleware with the PyKite application.

📌 Replaced the usage of the 'webob' library in the PyKite framework with custom request and response classes. This change allows us to have greater control and customization over request and response handling. The custom classes provide a more tailored solution for our framework's specific needs.

- Added custom 'Request' class to handle incoming HTTP requests.
- Added custom 'Response' class to generate HTTP responses.
- Updated PyKite to use the custom request and response classes.
- Removed 'webob' dependencies and references.

✅ This change improves the maintainability and flexibility of PyKite while reducing external dependencies.
