Expose the potential energy of chess ply

This library constructs a dictionary of chess piece threat and protection statuses, keyed by "rank and file" board positions.

Usage:

import chess
import json

from chess_coverage import Coverage

board = chess.Board()
board.push_san("e4")
board.push_san("d5")

c = Coverage(board)
cover = c.cover()

print(json.dumps(cover, indent=2, sort_keys=True))
