Enables to move to a frame by clicking on a trajectory via Alt + Dbl-LClick

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

We previously used a comparison to quality 100 for checking, if a point is a detection or not in the changed code. This was replaced by `80`, so a color-detection on e.g. a multicolormarker with code, which has quality 90, still gets counted as detection.

Also a helper function `isDetection` was created, so that this knowledge about the quality <-> detection relationship isn't scattered everywhere in the code.

There was an error, where a person, who was already deleted because they were merged with another, still got evaluated. During this evaluation, the person which got the index of the deleted one got processed, or a segmentation fault happened, when the deleted person was the last one.

This is fixed by setting `mStatus` to not only signal not being tracked, but also, already being merged away.

- Move last used export file from static var to member var
- Reset member var on opening a new project

This means PeTrack now requires C3D-files with joint positions added in. This results in a more accurate representation of the skeleton.

- 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

fix: Doesn't add the time offset given by the firstFrame parameter each time the project is read but only once. 

Enlarge CropRect to enable detection of code marker near edge of multicolormarker

- Add clang-format file
- Add scripts and format check for CI
    - script for checking the format (bash)
    - script for formatting the code (bash)
- Add format checking to CI
- Reformat project with clang-format

- Restrict access to parameters and force usage of setters and getters to ensure signals are being sent, when a parameter changes
- Some small changes for testability
- Some small fixes for bugs discovered during testing

- changed dialogue "Open MoCap" to "Manage MoCap"
- enable loading multiple MoCap-Files (or same with different offset)
- enable unloading MoCap-Files
- save all files in pet and load when opening project

- Create CodeMarkerOptions-Class
- Use CodeMarkerOptions-Class in findCodeMarker
- Use CodeMarkerOptions-Class in CodeMarkerWidget

- use ui file as base for the dialog
- use .zenodo.json for the list of authors
- add function to read authors from file
- copy authors list to binary path
