[Feat] Show sizes of model / lora / clip / etc

### Feature Idea

Either on the folder list or in some special node. I've downloaded so many models and lora's to test and I don't remember them all, some loras are 20mb, others are 600mb. It makes a huge difference on how much needs to be loaded into memory. If there was a list that showed the sizes of the files selected in the nodes that also totaled up the full sizes, it would be really helpful.

### Existing Solutions

I'm new to ComfyUI and I've spent a while looking for some way to get this information without having to dig into the folders in the file system and I couldn't find anything. I found a LoraInfo node, but that doesn't even provide the file size.
