Missing cond_decompdiff.pt checkpoint required by sample_diffusion_decomp_compose.py

Hi, thanks for your great work and for releasing the code and pretrained checkpoints!

When running the sampling script:

`scripts/sample_diffusion_decomp_compose.py`

I encountered the following error:

```
FileNotFoundError: [Errno 2] No such file or directory:
'logs_diffusion_full/pretrained_cond_decompdiff/cond_decompdiff.pt'
```

It seems that the script expects a checkpoint file named
cond_decompdiff.pt under logs_diffusion_full/pretrained_cond_decompdiff/, but only decompdiff.pt is provided in the released resources. Is cond_decompdiff.pt available somewhere?
