Switch Parcel to Webpack for bundler

[brianwchou]

Description

I'm hearing from each of you problems surrounding parcel as a bundling tool:

• nondescript error messages within the browser console
• slow building due to materialUI
• my parcel server gives me a 404
• problems with maintaining a consistent ES6 syntax

Considerations

Move to webpack for bundling and hot reloading
