@bevns should we merge this or leave it?

This pull request to snakes/go/pathy-snake adds new functionality to improve the snake's decision-making process, modifies existing functions to improve their efficiency, and improves the testing suite. The most important changes include marking cells surrounded by snakes as not walkable, modifying the chooseTargetCell function to use a new floodFill algorithm, and adding new functions to help the snake navigate the game board more efficiently.

Main functionality changes:

• snakes/go/pathy-snake/pathing.go: Added new functionality to choose the largest open area on the board as the target cell if no food is available, and marked cells surrounded by snakes as not walkable. (F188586a)
• snakes/go/pathy-snake/helpers.go: Modified the chooseTargetCell function to use a new floodFill algorithm, and added new helper functions to support it. (F55a0970)
• snakes/go/pathy-snake/paths.go: Added functions to help the snake navigate the game board more efficiently in func (p *Path) AtEnd() bool in snakes/go/pathy-snake/paths.go.

Testing improvements:

• snakes/go/pathy-snake/logic_test.go: Improved the testing suite by adding new test cases and reducing the number of iterations in TestFoodEating6 function. (F98a4544)

Other changes:

• snakes/go/pathy-snake/coord-funcs.go: Modified Surrounded function to exclude tail of other snakes from consideration when determining if a cell is surrounded.

I think we should just leave it. Its new but it didn't really preform any better.
