Provide scripts to build the provided models

[jheaff1]

Hi,

Would it be possible to provide the scripts used to build the models provided here - https://coral.ai/models/object-detection/

Specifically, I would like a version of https://github.com/google-coral/test_data/blob/master/ssd_mobilenet_v2_coco_quant_postprocess.tflite that detects only 4 of the COCO classes rather than all 90.

If the script to generate the model were provided, I could rework it as required.

Many thanks!
