Pull Request Overview
This PR introduces a new pathfinder library that implements the A* pathfinding algorithm in Luau. The library provides a generic pathfinding solution with support for partial path finding when a complete path cannot be found.
Key Changes:
- Implements A* pathfinding algorithm with configurable heuristics and traversal costs
- Provides partial pathfinding capability as a fallback option
- Includes comprehensive test coverage for heap data structure functionality

Debug print statement should be removed from test code as it adds unnecessary output during test execution.

The code calls openSet:IsEmpty() but the heap implementation being tested doesn't show an IsEmpty method. This will likely cause a runtime error.
