chore: update ipld and deps

[fsdiogo]

This makes ipld-explorer work with the new api changes from IPLD.

Also switched from source-map-explorer to webpack-bundle-analyzer.

Ref: ipfs/ipfs-webui#948

LGTM

I can't figure out why Travis is always failing. If I checkout master it fails there too.

You can debug the e2e tests by running DEBUG=true npm run test:e2e

I'm seeing a js-ipfs init error when running via puppeteer, which is weird, I don't see this when running locally.

Failed to initialise js-ipfs Error: No resolver found for codec "undefined"

The test passes on master, worth noting that you either have to be running app before starting npm run test:e2e or you can run them both with npm run test:e2e:ci

Oooh, i am able to recreate this locally if I delete all the indexedDB instances for the localhost:3000

So the good news is that the smoke test caught an issue, we need to update js-ipfs on this PR!
The bad news is that the latest js-ipfs contains fancy spread operators that create-react-app won't transpile in deps, so I need to go and raise PRs to fix that.
