Support fot TINY YOLO3

[SkalskiP]

The problem is related to this one: #665 . In addition to the layers mentioned in this issue, there is no support for yolo layer used in yolov3-tiny.cfg
Layer [yolo] not implemented
Do you plan to add such support? If so, when can you expect?

Yes would be helpful if configs for tiny-yolo are updated

For those wanting to convert Yolo-v3 from Darknet to TensorFlow:

Yolo-v3 support was recently added to DW2TF (see this PR).

Worth noting that unlike Darkflow which is also a runtime env for training/inference, DW2TF can only convert a Darknet model & weights to TensorFlow. Running training/inference on it would then be up to the user.
