Two main problems fixed here:
- offline tests will fail on a comparison failure (a mistake from the
re-write)
- art-group-info is committed to the repo and shared with every thread
(running the tests with 1 thread, for example on the CI, and locally
were producing different results)
art files are still not provided to the jak2 offline tests:
- `*-ag` files are not being output
- `art-elts.gc` is not complete, as a handful of files claim to be
missing stuff
lastly, in jak1's offline tests we were also running `tpage` and `*-vis`
files through the decompiler. This omits that (they came from the
`all_objs.json` file) -- is this an issue?
