Cleaning up of the main file

I have:

- Moved the tests in example/test.c to a separate file
- Renamed test.c to main.c for clarity
- Renamed the compilation target to swift_* to avoid confusion

No real code change, just re-organisation and renaming.

Updated the script fetching the cosmo volume ICs to point towards the updated ones.

I have modified the cosmoVolume ICs to be the output_001 file. They are also stored on the permanent stargate storage.
