Use resenet50 or another more advanced posenet DNN

[ivelin]

Is your feature request related to a problem? Please describe.
We currently use mobilnetv1 which works, but is now outperformed by newer DNNs used in PoseNet v2.0.

Describe the solution you'd like
Replace mobilnetv1 with resnet50 or a better model.

Additional Context
BlazePose is another recent development worth considering. Detects more keypoints than PoseNet 2.

@ivelin currently the TFLite model for posenet is only available in mobilnetv1.

Will look at BlazePose

BlazePose also look very interesting because it takes into account the central bodyline position as a reference metric in the model design.

@bhavikapanara see another recent development with impressive results: CenterNet

See TF models in the TensorFlow 2 Detection Model Zoo. Binaries in saved tf format, which can be converted to tflite format.
https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2_detection_zoo.md

Notice the high performance and dual purpose (object + keypoints) for CenterNet Resnet50 V1 FPN Keypoints 512x512 and CenterNet Resnet50 V2 Keypoints 512x512.

More on CenterNet and its various applications for object detection, pose keypoint estimation and object motion tracking.
