Production builds don't utilize loam-worker.min.js

They load `loam-worker.js` instead. This is problematic because `loam-worker.js` is roughly 3x the size of `loam-worker.min.js`. This may be able to be addressed at the same time as #58 .

Search the production build configuration and entry points for references to loam-worker.js and loam-worker.min.js. Verify that production builds load the minified worker and confirm the generated build uses the smaller file; check issue #58 for related context.
