- no split between include/src anymore
- more directories grouping files by their function
- CMakeLists.txt setup to support file lists in each subdir

Due to a mistake in !267, the error of the extrinsic calibration was calculated using the old calibration (i.e. all zeros on a new project). This leads to a terrible error and thusly to the rejection of the new calibration.

This commit fixes this by using the new extrinsic parameters to calculate the reprojection error. It also adds some simple regression tests for the extrinsic calibration to catch such mistakes earlier in the future.

Load AVG_PH instead of SUM_PH etc., since they are saved as such in the pet file

- that means moving the widget and all its signal/slot connections
- Create new interface `WorldImageCorrespondence` for all calculations between image/pixel coords and world coords (dispatches to `ExtrCalibration` when 3D, else uses old 2D coord sys)
- Moves the methods for wold image correspondence from the `ImageItem` to the newly created `CoordinateSystemBox`
- During this change: Make the 2D coord system not depend on `mapToItem`; its now using normal affine transformations (`QTransform`) instead, which incidentally should make #383 easier
- `imageSizeChanged` is now a slot of `Control`, such that `ImageItem` can call it without having a reference to `Control` by sending a signal (Following that: image item is now now directly depending on control anymore)
- Some include clean-up

- Introduces `ExtrinsicParameters`-Struct
- Extract `ExtrinsicBox` from `Control`

- Move "filter before" GroupBox into own widget
- Move "intrinsic" GroupBox into own widget
- Save intrinsic calibration in struct
- Use said struct as parameter for `CalibFilter`
- Add `setValue`-helper function for loading values into UI respecting min/max
- Move PeTrack-Version from Setter to Constructor of Petrack-object
- Add Unit-Tests

This
 - enables editing the .ui-file without changing control.h; reducing recompile time
 - encapsulates the widgets themselves from everything outside of Control

* Different minimum number of points
  * coplanar: 4
  * not coplanar: 6
* Check coplanarity, use different thresholds and give according error message

- Add large comment describing the approach taken
- Use OpenCV data types when possible to do explicit matrix-vector-calculations

- Stop Tracker inheriting from QVector, instead save TrackPerson in std::vector
- Save TrackPerson's in another class (new class PersonStorage)
- Move all functions directly accessing the trajectories in a writing/editing manner into this class
- Some small refactorings and documentation-comments

feat: Adds a custom MessageBox which does not break PeTrack when running with -platform offscreen (mostly CI)

Resolve "Custom MessageBox with logging capabilities and offscreen/scripting support"

Replaced QMessageBox with QDialog to get the correct layout without the instable hack to widen it.
