Accessibility of experiment logs for `HyperAgents`.

Hi, thanks for open-sourcing this project.

I ran into an issue when trying to access the experiment logs described in the README.

According to the README, the logs are stored as a multi-part ZIP archive and can be extracted with:

```bash
zip -s 0 outputs_os_parts.zip --out unsplit_logs.zip
unzip unsplit_outputs.zip
```

However, in the repo the files

- outputs_os_parts.zip
- outputs_os_parts.z01
- outputs_os_parts.z02
- ...
- outputs_os_parts.z08

are currently only Git LFS pointer files rather than the actual archive contents.

When I try to fetch them with Git LFS, all objects return 404, for example:

git lfs pull
--include='outputs_os_parts.zip,outputs_os_parts.z01,outputs_os_parts.z02,outputs_os_parts.z03,outputs_os_parts.z04,outputs_os_parts.z05,outputs_os_parts.z06,outputs_os_
parts.z07,outputs_os_parts.z08'

This fails with errors like:

Object does not exist on the server: [404] Object does not exist on the server
error: failed to fetch some objects from 'github.com/facebookresearch/...

There also seems to be a small inconsistency in the README commands:

- the first command outputs unsplit_logs.zip
- the second command tries to unzip unsplit_outputs.zip

So I am not sure whether:

1. the LFS objects were accidentally not uploaded,
2. the logs are hosted somewhere else,
3. or the README should be updated to clarify that these archives are not currently available.

Could you clari...
