   This model has been changed rapidly. Previous `hand_landmark.tflite` model 
is just FP32 model simply. Like this:

   However, current master `hand_landmark.tflite`'s weight is been quantized 
into FP16. Then it insert `dequantize` to FP32 execution, which is benefit for 
TFLite GPU execution. like this:

   we doesn't support this kind of quantized model yet. I suggest we current 
lock the `hand_landmark.tflite` into this commit: 
https://github.com/google/mediapipe/blob/c27a7c1e1064e66427ad0656f776155ab456f90b/mediapipe/models/hand_landmark.tflite
   
   @tqchen @leandron Could you accept this suggestion?
