Description

This PR fixes the comparison logic for the NuRouteSettings class and adds unit tests to ensure its correctness.

Changes

• Implemented proper hashCode and equality operator (==) in the NuRouteSettings class.
• Added unit tests to verify the merging of parameters and the comparison of NuRouteSettings instances.

Motivation and Context

The previous implementation of the NuRouteSettings class had issues with object comparison, causing tests to fail. This fix ensures that NuRouteSettings instances are compared correctly, which is crucial for the functionality of the routing system.

How Has This Been Tested?

• Added unit tests to check the merging of query, path, and extra parameters.
• Added unit tests to verify the equality of two NuRouteSettings instances with the same parameters.
