Espruino plugin for Rollup module bundler

Wow, yeah - that does look really promising. We'd need to ditch their service worker since the IDE has its own, but that should be pretty easy.

If we can get that in the IDE and it's under 500k that'd be perfect. Does it handle require ok? I didn't see that in any of the examples. I saw one of the examples uses Object.freeze which Espruino doesn't have at the moment, and I'm sure there are a few other issues we'd hit as well - it sure seems like it'd be worth it though :)
