You're making a basic 2D game, and you're trying to write a simple alogrithm that determines if the user can move the player in any given direction.

Given a 2D Array of binary digits (arr), and the players current position (pos) return True if the player can move up, down, left, and right. else return False.

A 0 indicates the player can move to that position while a 1 indicates a player can NOT move to that position.

Example:
arr = [[0, 1, 0, 0, 1],
       [1, 1, 0, 1, 1],
       [0, 0, 1, 0, 0],
       [0, 1, 0, 0, 1],
       [1, 0, 0, 1, 0]]
pos = (3,3)

This example should return False, as the player can move up or left, but the player can NOT move down or right.

The player can't move through an edge. You'll need to handle potential listIndex errors for edge positions.

The value of the players current position is irrelivent.
