How to save IMU stream in osf files

[joaocalen]

I'm creating a project using lidar which I log into a .osf every scan given by the lidar sensor. I found this easy using this method of class Writer:

void save(uint32_t stream_index, const LidarScan& scan,
const ouster::osf::ts_t timestamp);

But how can I save also IMU data? I have to use the save_message to store an array of bytes with the IMU data or is there a better way to do it?

Unfortunately OSF currently doesn't support IMU data yet.
If you need to preserve IMU use pcap or bag file format and if you are using the ouster-cli use the save_raw command.
