nice to have svg or png support

when execute print(board), it will show the ASCII, like python-shogi already have
print(board)

result

 l  n  s  g  k  g  s  n  l
 .  r  .  .  .  .  .  b  .
 p  p  p  p  p  p  p  p  p
 .  .  .  .  .  .  .  .  .

 P  P  P  P  P  P  P  P  P
 .  B  .  .  .  .  .  R  .
 L  N  S  G  K  G  S  N  L

when execute
board

result
Board('lnsgkgsnl/1r5b1/ppppppppp/9/9/9/PPPPPPPPP/1B5R1/LNSGKGSNL b - 1')

expected result like in python-chess,
when execute board it will get svg or png draw
