Add Apache ECharts HTTP Export Server

Currently, there is no HTTP Export Server ( Server Side Rendering ) for ECharts. In view of this, we created Apache ECharts HTTP Export Server. The export server is a Node.js-based service, which is easy to install and integrate on any system. It accepts either JSON-formatted chart options or SVGs, together with additional resources, and uses node canvas to render Apache ECharts charts to images (PNG, JPG, SVG , PDF and Base64) to be sent back to the user.The application can be used either as a CLI (Command Line Interface), as an HTTP server, or as a node.js module..

The repo is here.

Thank you and look forward to contributing to this list.
