[Feature] Tracker on a table detection

[loucass003]

Have the tracker tell if the user did the imu calibration or not.
This should be enabled only on IMUs that require it like the BNO

it could simply be a boolean if it is done or not.

the check should be something like:

if the tracker accelerometer reported the gravitational constant for a few seconds then we can assume they performed the calibration
