VQGAN models license

[Aspie96]

Hi!

The vqgan_imagenet_f16_16384 model in particular has been used by other interesting projects.

This repository has an open source license (the MIT license), but the model is hosted separately and is not actually contained in the repository, merely linked from it.

Would you consider adding a license for the provided VQGAN models, and for vqgan_imagenet_f16_16384 in particular?

I am aware of the fact that you don't own the dataset or the images, but, if you did all of the training, it would still be useful under the theory that models aren't derivatives of the data, but they are copyrightable by those who did the training.

I think using the same license as that of the repo would simplify things.
