convert centernet_hourglass for keypoints detection to TFLite model

1. The entire URL of the file you are using

https://github.com/tensorflow/models/blob/master/research/object_detection/export_tflite_graph_tf2.py

2. Describe the feature you request

Ability to convert centernet_hourglass for keypoints detection to TFLite model

3. Additional context

In order to speed-up the spread of mobile applications that employ Tensorflow model, I think is pretty needed being able to convert such a kind of model to the mobile format.

4. Are you willing to contribute it? (Yes or No)

If possible, Yes.

Can you provide any information on the willingness of the development of such a feature?
Can you give me some information (practical implementation) on how it will be possible to achieve that?

Thankyou very much!!
