`dpt_hybrid-midas-501f0c75.pt` was in the wrong position in readme.md

[danyow-cheung]

In Currently readme.md ,the origin project structure was wrong

StableVideo
├── ...
├── ckpt
│   ├── cldm_v15.yaml
|   ├── dpt_hybrid-midas-501f0c75.pt
│   ├── control_sd15_canny.pth
│   └── control_sd15_depth.pth
├── data
│   └── car-turn
│       ├── checkpoint # NLA models are stored here
│       ├── car-turn # contains video frames
│       ├── ...
│   ├── blackswan
│   ├── ...
└── ...

the correct project structure should be like

StableVideo
├── ...
├── annotator
│   └── ckpts
│       ├── cdpt_hybrid-midas-501f0c75.pt
├── ckpt
│   ├── cldm_v15.yaml
│   ├── control_sd15_canny.pth
│   └── control_sd15_depth.pth
├── data
│   └── car-turn
│       ├── checkpoint # NLA models are stored here
│       ├── car-turn # contains video frames

└── ...

Besides, in case people need to install the cdpt_hybrid-midas-501f0c75.pt from huggingfacehub , we have to install these packages below

pip install tb-nightly
pip install basicsr
