updated to v0.1.3

bugfix: The perfect clear algorithm now has additional tests to remove all of the solutions that includes impossible rotation/placement.

quality of life: in practice mode, the player can now hold the piece as much as he want and isnt limited to once per piece.

currently working on: 

-downstacking algorithm which hints where to place the piece to downstack better

-AI that allows the user to copy paste a screenshot of a board and said board will be reproduced in game
