An example of path finding algorithm visualizer using gg module

Example: Adding A* Pathfinding Visualization

Description

This pull request adds a new example demonstrating the usage of A* pathfinding algorithm in the V language. The example uses the gg graphics library to visualize the algorithm's execution.

Changes Made

• Added a new file aStar.v with the A* pathfinding visualization example.
• Utilized the gg library for graphical visualization.

Why

I think because lack of actually documentation its hard to use library also other example lacks detailed comment i tried to write my code with comment on most of the part

Additional Notes

• The example assumes the availability of the gg library, and users should install it before running the example.
• Documentation for the gg library is still under construction, and this example serves as a practical reference for using the library in the context of A* pathfinding.

Thanks for considering this contribution!
