Describe the operator

Rearranges input tensor in blocks. Same behavior as https://pytorch.org/cppdocs/api/function_namespaceat_1a979fbf85d8c7362d60d766bbf1639f10.html

Can this operator be constructed using existing onnx operators?

If so, why not add it as a function?

Is this operator used by any model currently? Which one?

Used by torch.fold.

Enables model SS-DCNet
Enables model DSTT
