Using multiple processes for a single device can result in the same image names being saved.

### Feature Idea

A single device has multiple graphics cards and runs multiple comfyui applications. When they save images at the same time, it results in identical file names.
```
class SaveImage:
def __init__(self):
self.output_dir = folder_paths.get_output_directory()
self.type = "output"
self.prefix_append = ""
self.compress_level = 4
```
to
```
class SaveImage:
def __init__(self):
self.output_dir = folder_paths.get_output_directory()
self.type = "output"
self.prefix_append = str(args.cuda_device or "")
self.compress_level = 4
```
