Change output filename

[bveldkamp]

This is more of a question than an issue.

Is it possible to have npm run build generate a filename other than the default main.js? We develop several libraries that are all called main.js now.
The only way I found so far is to modify webpack.config.js inside the @vertigis/web-sdk/config folder, but I don't think that is very maintainable. Can we override or extend this file somehow?
