Provide device calibration

[taketook34]

Need solution to calibrate MPU (script, program module)

[taketook34]

Librobotcontrol has got calibration functions and store result in special files in /var/lib/robotcontrol. So it is proposed not to provide any updates to software because librobotcontrol utils fulfill all requirements and just write in user guide commands how to calibrate device

@AksonovSergei need you mention about this

Hi,
how often should we run calibration?

[taketook34]

Gyroscope and accelerometr need to calibrate once in several month. Magnitometer need to calibrate when we move device in another space

[AksonovSergei]

ok. let's start with instruction how to do.

@ChVictoria Also tested calibration using robotcontrol and said that she is satisfied.
