Remove all camera systems except IDS uEye from sys folder

- Deleted all subdirectories from sys/ except idsueye/
- Updated sys/CMakeLists.txt to only include idsueye subdirectory
- Updated main CMakeLists.txt to only search for IDSuEye package
- Removed find_package() calls for: Bitflow, NIIMAQ, NIIMAQdx, FreeImage,
  OpenCV, Aptina, EDT, Euresys, GigESim, Imperx, ImperxSDI, IOtechDaqX,
  KAYA, Matrox, Phoenix, Pleora, Pylon, QCam, Sapera, and XCLIB

The project now exclusively supports IDS uEye cameras in the sys folder.
