Log Analysis Viewer: Shows IMU Orientation in Radians, but with Degrees unit

[NicoAleman]

VESC Logs track IMU Orientation values as radians. The Log Analysis feature in VESC Tool displays these values as is, but truncated to the tenths place, with a degrees unit. It seems the intention was to convert to degrees, which I agree is most sensical. However, the conversion actually never takes place.

I have pushed a fix that changes it to rad and uses three decimal places. I agree that degrees would be better, but that would break compatibility with old logs or require code that applies a conversion to the IMU fields, which makes them inconsistent with all other fields.
