Add IMU Calibration Script

• OAK-D showing wrong heading from rotation_vector.
• Provide a script to calibrate IMU in Examples/IMU

@iam-shanmukha at the moment we don't perform factory calibration for IMU, and we don't have an ETA when will be added, because we are quite busy with priority support. (@saching13 can correct me on that).

Just wondered if there are any news on that?

If not, where could I put in calibration numbers so that they are used, e.g. in the calculation for the rotation vector. Thanks!

No update yet.
We are working on including static extrinsics from the design info into the api in next 2 months.

You can add the extrinsics into CalibrationHandler which carries the camera calibration here

Thanks for the fast reply!
As far as I see it, this only helps for the relative orientation and translation of the IMU relative to the camera?
Just to doublecheck: It does not help for setting calibration parameters of the magnetometer, right?
