Add components from wc-ribbon repo

[pkalita-lbl]

Part of #2

These changes bring the components from the wc-ribbon repo. The structure here is to simply bring all the components into a single project (i.e. there is only one package.json file) and not attempt to do a multi-project monorepo for now.

While copying code from the source repo over the following cleanup was done:

• Use go-* naming convention for component subdirectories. Note that the names of component classes and their associated tag names have not changed yet.
• Move utilities that are specific to a single component to a src/components/{component-name}/utils.ts file and put code that is shared among multiple components in src/globals
• Use TypeScript interfaces instead of actual classes in src/globals/models.js
• Drop some unused code
