Implement ViewROI and base classes (#287)

* Implement ViewROI and base classes * Clean up Orientable header * Move tgl to tgl subdirectory, and use target_include_directories * Move classes to submodules * Fix some missed references * Fix/match UpdateWorldData * Renaming / removing MxTypes / refactoring * Consistent naming for Matrix * Adjust format action * Add Vector3/Vector4 to Data vector * Add TGL comment * Add a comment about Matrix4Impl * Add ROI comment --------- Co-authored-by: Anonymous Maarten <anonymous.maarten@gmail.com> Co-authored-by: Christian Semmler <mail@csemmler.com>
