Update rollup to the latest version 🚀

[greenkeeper[bot]]

Version 0.49.3 of rollup just got published.

Dependency	rollup
Current Version	0.46.3
Type	devDependency

The version 0.49.3 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of rollup. Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.
