Configure engines

[AttackingOrDefending]

• Added configure to engines, to set many options in one line.
• Fixed a bug for frisian and frysk!.
• Fixed another bug where there was an extra condition and self.men_can_capture_backwards, which was not needed. It didn't cause any problems because there is no variant supported by pydraughts that would not work because of this line.
• Renamed PlayResult.resign to PlayResult.resigned.
• Added cwd to DXP engines.
• A few type hint corrections.
