Codenames: Duet mode

[HippoPenguin]

Request to add the option to put the game into "Codenames: Duet" mode, with the mechanics of the "Codenames: Duet" game.

Would require:

• Having two code grids (see the Codenames: duet rules for how the grid colours match)
• Each side on separate teams.
• A limit on the number of clues allowed.
• A limit on mistakes.
• Either randomising the mistakes/clues allowed. using the official "mission" maps or custom "mission" maps.

Will add this feature in, but maybe push back to a later release (2.0.0/3.0.0).
