Refactor build system to use rollup

Due to lack of interest from the repositories owners I will close this.

Hi @tdeekens —

Sorry about that! We missed this one.

We do favor anything that makes it easier for developers to use our SDK. So I'm curious to hear more about this.

I'm not very familiar with Rollup. At a glance, it seems like the SDK would also be (written and) usable as an ES6 module, in addition to UMD, ESM and CJS modules. Would updating to Webpack 2 achieve the same thing?

[tdeekens]

You can achieve the same thing using webpack@2. However, it's generally kind of true that webpack is for apps and rollup for libraries. It's just a bit simpler to configure and doesn't come with loads of features libraries won't need (e.g. code splitting).

[tdeekens]

So how would you like to go about this? What would be a preferred way? Should I open a PR removing webpack for rollup trying to show some benefits in using it?

That would be great, thanks!
