Switch camera extrinsic, camera pitch parameters to radians

[tuxbotix]

It was not nice to find that the units aren't consistant. At least we should add a suffix if we deviate from the conventions (i.e. extrinsic_rotations_deg or better to clean things up.

As I'm quite busy testing the calibration setup and working on fine tuning, someone else can do this, could also be a newbie task (with some helo) as the work itself isn't too hard.

TODOs:

• Change manual & automatic calibration panels to save values in radians (while visualising in degrees for convenience
• Change crates/control/src/camera_matrix_calculator.rs to read parameters as radians
• ^Also check if we directly read the camera parameters elsewhere and modify them
• Update the parameter JSON files! (some quick n dirty rust/ pythons script?)
