Refactor namespaces and enhance code structure (#8)

* Refactor namespaces and enhance code structure

Key changes include:
- Enhanced organization of the `RqlExpression` class with method regions for better readability.
- Updated `RqlOperators` and `RqlSelectModes` enums to include the `[Flags]` attribute for improved usability.
- Refactored `RqlPropertyAttribute` for streamlined handling of actions, operators, and selection modes.
- Introduced interfaces like `IRqlNode` and `IRqlQueryable` to promote better object-oriented design.
- Restructured `RqlSettings` and related classes for cohesive configuration management.
- Updated test files to ensure relevance and functionality with the new structure.

These changes aim to improve modularity, readability, and maintainability while adhering to modern C# practices.

* namespace adjustments

* IRqlMapAccessor moved to abstractions

* Refactor RQL configuration and result handling
