Testing for pull requests and releases

Here's a list of things to test before publishing releases, and ideally before merging PRs into the master branch.

• Test all supported dataset formats: RAW, DICOM, NRRD, Nifti, PARCHT, image sequence. Get sample datasets here.
• Test on Windows and Linux.
• Test Unity 2019+
• Test all render modes: DVR, isosurface, maximum intensity projection.
• Test 1D and 2D transfer functions.
• Test slice renderer.
• Test cross section tools (plane, box, sphere).
• Test serialisation: Save imported dataset to scene (and re-load scene) and as prefab.
• Test serialisation: Make sure imported datasets that were saved with old version still work.
