Process embedded source maps

[THemming]

I'm trying to use a grunt-concat-sourcemap task after a grunt-browserify task but I'm getting a warning as grunt-concat-sourcemap is trying to use the encoded string as a filename to open.

Browserify embeds the source map as a base64 encoded string, i.e: data:application/json;base64.

Could this plugin detect the embedded source map, decode it and use it directly?

The plugin should consume a base64 encoded source map. This is the issue to be resolved in this plugin.
