Is your feature request related to a problem? Please describe

Xtreme1 has its own annotation format, and this is necessary cause Xtreme1 needs record more and more details according to the growth of features.

However, we still need language tool to help people convert this dedicated format to some common format e.g. Coco. This is very important since the deep learning frameworks or tools already support the Coco format otherwise every people need to write the converting code.

With this SDK, Xtreme1 can be more easy to provide some new features like exporting Coco format directly in the Web Console without duplicate effect.
