修改概述：优化镜头平滑跟随逻辑，解决视角抖动问题
修改的详细描述
1.调整镜头平滑插值系数：在 run_simulation.py 的 set_spectator_smooth 函数中，将线性插值系数 t 从 0.1 调整为 0.2，加快视角对车辆运动的响应速度，减少滞后累积导致的抖动。
2.统一仿真帧率与视角更新频率：在 carla_environment.py 中，将 fixed_delta_seconds 从 1/20 改为 1/30，与 run_simulation.py 中 clock.tick(30) 保持一致，避免因时序不同步引发的周期性抖动。
经过了什么样的测试？
操作系统：Windows 11
Python 版本：3.7.5（虚拟环境，通过 VSCode 创建与激活）
CARLA 版本：0.9.11
运行结果：
修改前镜头抖动：
555.mp4
修改后镜头p平滑移动：
666.mp4
