Release/2.1

[violetweir]

您好我对PR不太熟悉这里我就把我仓库修改的链接给您一下吧。 我这里主要是看到ppyolo是用paddledetection进行迭代的，然后我的项目是要对ppyolov2做了一个修改，我把ppyolov2的backbone更换为了botnet，然后原本我是打算在paddledetection的backbone的存放界面写一个botnet呢，但是因为我不知道怎么进行相关配置，就比如我写了一个botnet.py我不知道怎么在网络结构配置中引用botnet最后我就把resnet.py给改成了botnet https://github.com/violetweir/PaddleDetection 然后我在ai studio里面写了一个项目就是用paddledetection复现botnet并作为backbone应用到项目的。 https://aistudio.baidu.com/aistudio/projectdetail/2265776?channelType=0&channel=0 我真的十分希望能教一下怎么规范化的给paddledetection添加新功能，太谢谢了。
