Utility to handle Pipe mode input like PipeModeDatset in tensorflow_extensions

**Describe the feature you'd like**
Utility to handle Pipe mode input like pipmodeDatset in https://github.com/aws/sagemaker-tensorflow-extensions/blob/master/src/sagemaker_tensorflow/pipemode.py.
Is there anything similar for mxnet ecosystem?

The issue references sagemaker_tensorflow/pipemode.py as an example but does not name any target files or tests in this repository. Start by reviewing that reference and the toolkit's MXNet training entry points, then clarify the required Pipe mode behavior and acceptance criteria before estimating implementation or tests.
