we might need to add better tests to the repo but the CI should work

Closes #3

[StRigaud]

I am facing some issues, I fail to move the demo test with imglib2 into a test, like I did for the ImagePlus demo.

• Error conserning some package slf4j
• the ImgLib2 playground (YetAnotherPlaygroundImgLib2) does not run anymore and I do not think this is related to CLIJ3

Also it seems that we can only test on macos-13 run which are the only one left with native OCL device. Other OSs would require to install an equivalent to pocl or oclgrind which idk yet how to do this for Java.
