Reduce size of bundle

[abrahamq]

vendor bundle is ~7 mb before compression. I don't think tree shaking is working.

takes around ~50 seconds on first load using the fastest 4g speed available (1500 kb/s). Super important we fix this before next deployment. No one will stick around for a minute to watch it load.

@abrahamq is this still a valid issue?

[abrahamq]

Although we've reduced the bundle size to ~4MB combined, it still takes 20 seconds to download on fast 4g and about a minute on 3g. Maybe we should try doing more lazy loading of imports? I'm not really sure how to go about dealing with this.

We didn't have compression enabled on aws cloudfront. After enabling it, the production size went down 50%. Closing this issue for now. Let's be more careful about adding external dependencies in the future.

maybe we lazy load the info pane? I'm not sure how else to reduce the size further. Internet says that 40% of people won't wait ~5s for our site to load (best case 4g).
