Implementing YOLOv4

[kartikdutt18]

Hey everyone, I will be working on implementing YOLOv4 in mlpack for a college project. I'm opening this issue to prevent conflicts incase someone also starts working on it.

Thanks.

Hello @kartikdutt18 are you still working on implementing YOLOv4 in mlpack. If not I want to take up this project and include it as a part of my GSoC deliverable.

Thanks
