Draft: Add stereolabs zed mini driver
scope of this merge request:
- add stereolabs zed mini driver to use zed c++ sdk to stream 6dof
- optional: camera stream added to gui target
out of scope changes, that will be reverted before coming out of draft:
- readme fix
- some messages added in cmake
- added condition for test-building
I'll fix the commit history later.
I used the realsense driver as a starting point, so I used the autoprober thing instead of the libusb with only pid and vid identification. if that doesnt make sense please tell me and I'll change it.
