test: add default track selection testing
The amount of options we have that are related track selection is insane and touching any of this stuff is scary. Add some track selection testing to the CI to hopefully make it slightly less scary to touch any of that. Since trying to work in media files from some outside source would be a pain and need to live in some repo somewhere, it's nicer to just generate dummy files on the fly with ffmpeg during the ci runs and use that. Obviously, the actual tests themselves could be even more thorough (external tracks were not even considered), but this is more than a good enough start for now.
