Demote some dependencies to devDependencies

[dzbarsky]

It's currently not possible to install this package because it depends on a private repo...

➜  sdk git:(master) ✗ npm install @airtable/blocks -f                                                                                                                                                                                                                   ~/blocks/packages/sdk

While I was here:

• the lodash dep is unused
• removed around 500 files from the distribution that users probably don't care about. (By the way, the stories couldn't even work, because one of them depends on prettier which is a devDep...)

This needs the lockfile to be regenerated; I can't do that because of
