Add InternImage-H Results

[praeclarumjj3]

This PR enables running OneFormer with the InternImage-H backbone.

TODO

• Train on ADE20K with 896x896 image resolution and emb_dim=256.
• Train on Cityscapes with emb_dim=256.
• Train on COCO with emb_dim=1024.
• Train on Mapillary with emb_dim=1024.
• Finetune ADE20K and Cityscapes with emb_dim=1024.

Awesome to see that OneFormer is improved even further! 🤩

When trying it out, I found that the new Mapillary weight file (https://shi-labs.com/projects/oneformer/mapillary/250_16_intern_image_h_oneformer_mapillary_300k_1024.pth) seems to be incomplete. I get the following error when loading it in pytorch:

torch.load('../250_16_intern_image_h_oneformer_mapillary_300k_1024.pth.1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/pauls/anaconda3/envs/oneformer/lib/python3.8/site-packages/torch/serialization.py", line 600, in load
    with _open_zipfile_reader(opened_file) as opened_zipfile:

    super(_open_zipfile_reader, self).__init__(torch._C.PyTorchFileReader(name_or_buffer))
RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

I cross-checked by successfully using the other new weights (COCO, CS). Also, zip is reporting an incomplete file when listing/reparing:

zip -FF 250_16_intern_image_h_oneformer_mapillary_300k_1024.pth --out 250_16_intern_image_h_oneformer_mapillary_300k_1024_repaired.pth

Would you mind checking the file and, if necessary, reuploading it? Thanks a lot already!
