End a game by timeout

[xc6pm]

Is your feature request related to a problem? Please describe.
Timeout is already defined on the EndGame enum, however I don't see a way for ending a game and marking it as timeout. The best I can do at the moment is to make the player who ran out of time resign.

Describe the solution you'd like
Add a method like EndByTimeout.

Describe alternatives you've considered
Resigning the timed out player.
