Simplify Import Statement and Improve Test Coverage for secured Pac…

…kage (#19)

### Description

This PR simplifies the import statement for the `Secured` class and adds unit tests to achieve almost 100% coverage for `secured/secured.py`.

---

### Related Issue

- Fixes #18 

---

### Changes Made

- Simplified the import statement for the `Secured` class from `from secured.secured import Secured` to `from secured import Secured`.
- Updated `secured/__init__.py` to include `Secured` in `__all__` for a cleaner import.
- Added comprehensive unit tests for the `Secured` class.
