v1.3 but without bugs (?)

Fixed 3 bugs :

• Threshold not working as expected
• Some fens could not be read anymore
• When exploring multiple games/positions only the last one was saved

v1.3

Finally some more functionalities !

• Score is now normalized
• Added --threshold option
• Now supporting less common fen formats
• Fixed minor bugs
• Refactored most of the code

v1.2.1 (Finally bugfree ?)

• Default behavior switched to not appending foreshadowed continuation to terminal nodes. Use --appending to restore old behavior.
• Script no longer crashes when the score is not given in centipawns.
• Fixed major bug which occurred when one player was in checkmate or the position was drawn.
• Major refactoring of core functions. Script is now 100x times faster at very low nodes count. and slightly faster overall

• Added option '--no-appending' as suggested by @jupiter
• Output filename is now shorter and clearer

If you think things are missing don't hesitate to point it out by making an issue.
I will try to add it as soon as possible.
