update to conform to python-chess v1.0+

[dman82499]

The python-chess module now uses a different interface for chess.uci. I am willing to make a pull request to update it to the current library standard, if the author of this repository is still here.

@dman82499 , I am sorry, I have too many projects going on right now. I will have no time to check your PR. But you can become the manager of the repo if you want !
