Canvas support for usage in nodejs

[JaneX8]

Unfortunately it is now only possible to generate canvas images using a browser. I would like to generate SVGs with nodejs alone.

This works perfectly https://github.com/lindell/JsBarcode#nodejs but bwip-js supports more types of barcodes so it would be great is bwip-js gets this node canvas support too.

There is example code provided to render SVG output. Please have a look at https://github.com/metafloor/bwip-js/tree/master/examples:

$ cd /your/path/to/node_modules/bwip-js/examples
