Feature: Support for encore loaders and plugins

[bildschirmartist]

Hello,
we use this extension to develop a Contao Theme Bundle that takes advantage of Webpack and which we can include in multiple Contao instances.
With the basic functionalities of Encore this is working great!

But beyond that we would also like to use other plugins and loaders, such as this one: https://www.npmjs.com/package/svg-spritemap-webpack-plugin.

Therefore, it would be great to be able to add these, with appropriate configuration, as EncoreEntry as well.

Hi, that looks like a very good idea to let encore entries enable loaders/ plugins. But to implement such a future we need a good concept (how do we the configuration, how to handle multiple entries configuring the same plugin) and time (which is always short especially for things we do not need for current projects). You're very welcome to provide an concept or do an concept PR :)
