Add training data

[ashrafbay]

The model is very good and has a very broad concept
But there is a slight problem in the anatomy of the body and this is due to the lack of sufficient training data especially in complex poses and sports such as gymnastics
So I provide a huge set of free training data and I think it is open source
A wide range of sports such as gymnastics, diving, skiing and others are available with very high quality
And according to my experience in training some models, it has improved the anatomy of the body and difficult poses significantly
