text: Title: [Feature request] Provide a means to convert to numpy array without byteswapping
  Body: ### System information
  
  ONNX 1.15
  
  ### What is the problem that this feature solves?
  
  Issue onnx/tensorflow-onnx#1902 in tf2onnx occurs on big endian systems, and it is my observation that attributes which end up converting to integers are incorrectly byteswapped because the original data resided within a tensor. If `numpy_helper.to_array()` could be updated to optionally not perform byteswapping, then that could help solve this issue.
  
  ### Alternatives considered
  
  As an alternative, additional logic could be added in tf2onnx to perform byteswapping on the data again, but this seems excessive.
  
  ### Describe the feature
  
  I believe this feature is necessary to improve support for big endian systems.
