Compass calibration should show diagonals and offdiagonals

It would be nice if the Onboard Mag Calibration section showed the final diagonals and offdiagonals instead of just the offsets.

We've recently discovered an issue with the onboard compass calibration in which the diagonals and offdiagonals are not being updated. I'm not sure it's all that much use to users but it might be nice if the display of these three bits of data was displayed in a table or something instead of just as a blob of text.


Start by locating the Onboard Mag Calibration section in the Mission Planner desktop UI and trace how it currently displays the offsets. Check how the diagonal and offdiagonal calibration values are obtained and updated. Done means the final values are shown clearly, preferably in a table, and the display reflects the completed calibration.
