Resize ControlLoRA

[woct0rdho]

This PR is based on #2057 . It supports resizing ControlLoRA (LoRA version of ControlNet). We can save a ControlLoRA using ControlLoraSave node in stability-ComfyUI-nodes, then resize it using networks/resize_lora.py.

For example, I've uploaded some resized ControlLoRAs in https://huggingface.co/woctordho/sdxl-control-lora . They help save some VRAM from 2.5 GB (the original ControlNet) to 0.3 GB (the resized ControlLoRA).

Thank you, this is a good idea to generalize the converter. Could you please check the Copilot review?
I also think that passing LORAFMT as a parameter instead of globally is a good idea.

[woct0rdho]

I agree that using global variables is a bad practice (it was a quick patch based on the previous PR). I'll refactor it.

[woct0rdho]

I've refactored the code to avoid the mutable global variable (there is no need to rename lora_down and lora_up in param_dict). I've tested that the 3 LoRA formats can be converted by this script, and they work as intended in ComfyUI.

Thank you for update! This looks good.
