Add [MAT](https://github.com/fenglinglwb/MAT) model


High-Resolution Strategy configuration

Each model has its own independent High-Resolution Strategy configuration.

Download Mask

Enable download inpainting mask when download result



New Model: [ZITS](https://github.com/DQiaole/ZITS_inpainting)

Image is from [ZITS](https://github.com/DQiaole/ZITS_inpainting) paper. I didn't find a good example to show the advantages of ZITS and let me know if you have a good example. There can also be possible problems with my code, if you find them, please let me know too!

- Redo: Now you can `Redo` the inpainting result

- Gradually Inpainting(enabled by default): Perform inpainting on the last inpainting result, this makes it possible to further improve the inpainting result. It also helps to keep unmasked previous inpainting regions unchanged

- `Start New` change to `Upload New`: upload new file at editor page

latent-diffusion model add [plms](https://arxiv.org/abs/2202.09778) sampler. In general plms can get better results with fewer steps.

Original Image

ddim sampler steps=5

plms sampler steps=5

- bug fix: fix sizeLimit reset after inpainting.
- ldm model fp16 support, use less GPU memory. Benchmark on 3090
