Support for YOLO v3

[ThabrezAhmed]

First of all, thanks for creating this awesome package. Great work 🎉

Does this package supports YOLO V3 ?

I tried running the tiny YOLO V2 model from demo project. It works well.

When we tried to run YOLO3 keras model converted to tflite, we are not getting result/ detection.

P.S the same converted model is yielding result when we tried to run on standalone server.

@shaqian i want to add YOLO4 using this package. Will there be support on adding YOLO4 in future?
