zhoujie 44c37ec769 ✨ feat(gps): 新增GPS海拔数据支持并优化系统配置 
- 在数据包结构中新增gps_altitude字段以支持海拔数据存储
- 更新PackData和PackCorrectedData系列函数，增加altitude参数
- 移除timestamp字段以精简数据包结构，提高传输效率
- 优化GPS数据处理逻辑，取消GPS有效性检查，直接使用原始GPS数据
- 将调试输出和监控保存间隔统一调整为30秒，降低系统负载
- 将数据存储文件最大大小从20MB提升至100MB，支持更长时间数据采集
- 将GPS数据超时时间从2秒延长至10秒，提高在弱信号环境下的稳定性

🔧 chore(spi): 调整SPI配置以优化通信稳定性

- 将所有SPI接口的时钟相位从SPI_PHASE_1EDGE调整为SPI_PHASE_2EDGE
- 将SPI1的波特率预分频器从4调整为8，降低通信速率以提高稳定性
- 更新STM32CubeMX配置文件(.ioc)以反映SPI配置变更

📝 docs(script): 新增高性能数据分析工具脚本

- 创建atem_parse.py脚本，提供数据解析和可视化功能
- 支持V1/V2数据格式解析，V2版本包含GPS经纬度和海拔数据
- 实现串口实时数据接收和GPS动态模拟输出功能
- 提供波形图、轨迹图和海拔曲线等多标签可视化界面
- 包含数据表格展示和CSV导出功能，支持高性能大数据处理
