add HunYuanDiT

The functionality has been implemented first, but further optimization is needed. If it is possible to merge, need to modify the README first

Thank you for working on this! There's a few things that I think should be changed, let me know what you think:

First, I feel like loading from just one folder with fixed names is less than clear. The CLIP/mT5 model being separately selectable would make more sense, then we can split it up like this:

• chinese-roberta-wwm-ext-large.bin goes in models/clip (technically not a CLIP model, not sure why they named it that?)
• mt5-xl.bin goes in models/t5
• HunyuanDiT.pt goes in models/unet

(the user would have to rename the files from just "pytorch_model.bin")

Second, there's a lot of small changes that need to be made, and some code redundancy that needs removed. For example, the MT5/CLIP are currently non-standard, and don't work with the regular text encode node, though this might be hard to implement.

I can't really merge this as-is, but I can adapt/fix parts of it and add it to the main repo if that works for you. I'll add your name to the readme for credit.

Oh, and I noticed you're saving the embeddings for testing. Could you send me those for easy debugging? clip_prompt_embeds.pt, etc. It would help a lot.

I agree with what you said. I have added support for custom resolution, batch image generation, and img2img generation. If there is anything worth referring to, you can go directly https://github.com/chaojie/ComfyUI_ExtraModels

I've got the initial proof of concept working (trying to integrate it more closely). Custom resolutions/etc will still need more work and it's a WIP at the moment, with a lot of it using the original reference code.

Again, thank you for your work, I will continue to reference it as I fix things.
