feat(wits): 添加WITS数据验证和字段规则配置

- 在model.__init__.py中新增REQUIRED_SIMPLIFIED_FIELD_RULES和REQUIRED_TRANSMISSION_CHANNELS导出
- 移除app/mqtt_sender.py中的MQTT发送功能，禁用相关逻辑
- 在model/wits.py中添加WITS字段验证规则和传输通道映射配置
- 实现validate_required_wits_fields函数进行必填字段验证
- 在WitsData类中添加__post_init__方法执行字段验证
- 为wits_sender.py添加传输值验证和数据包验证功能
- 更新随机WITS数据生成逻辑，使用真实钻井参数范围
- 实现数据包解析和验证功能，确保必传字段完整性
