Inline source map with extended data uri syntax causes an error

[asapach]

One of the libraries I'm using has the following inline source map:

//# sourceMappingURL=data:application/json;charset=utf-8;base64,...

This doesn't match the regexp: /data:[^;\n]+;base64,(.*)/, because it specifies an encoding in the mediatype, but it's perfectly valid according to the spec: https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs

This results in the wrong code path being taken and the data URI is interpreted as a URL, which results in an error: Cannot find SourceMap 'data:application/json;charset=utf-8;base64,...

I suggest relaxing the regexp to allow semicolon: /data:[^\n]+;base64,(.*)/

this is fixed by https://github.com/webpack-contrib/source-map-loader/pull/21/files, it's almost 2 months old now, can we get this fixed pushed through?
