Deployment / Build process: release more versions, reduce bundle size

[ryan-williams]

• support mode with <link/>/<script/> tags, to reduce initial bundle size
• build prod/dev releases as different files under dist/
• DEP0005 deprecation warning during npm run build
• create Lambda that compiles index.html with various default configs set (or e.g. sql.js mode)

Audit/reduce bundle size

2021-12-29: I imported just the S3 client from aws-sdk (thx @jasonprado!) and that reduced the production index.html from 4MB to 1.3MB 🎉

2021-12-27: I spent a while optimizing imports and things and shaved 35 bytes off a 4MB package. I think I webpack is already "tree-shaking" in some default way; not sure if there is a much more aggressive version that can be set up, or if I just have to cut out some dependencies.

Would be good to compare against an index.html that <link>s/<script>s in its deps (1st bullet above).
