Create Big Cannons:Simple Scope

Turret adapted for the HeadTrack—turret assembled from two turret bases in CBC-CompactMount Fixed the issue where the barrel direction didn't match the center of the view when aiming down sights (how it works now: when you aim down sights, the barrel moves toward the center of the view, and a green outline shows the actual aiming direction of the turret)

为头瞄适配了—CBC-CompactMount-中的两个炮台底座组装的炮台。 修复了头瞄启用时炮管实际方向与镜头中心不重合问题。（解决逻辑：开启头瞄时，炮口方向会向镜头中心靠拢，同时添加了绿色框线标识炮台实际瞄准方向）
