SASS color file parser (4h)

based on a list of colors, generate the colors page.

Define how to write the sass file for colors and make sure the following things are included & extractable in a json

- `name`
(automatically show the `.c-`, `.bg-` classes)
(automatically show the `$c-` variable name)
- `value`
- `description`
- `subcolorOf`
(this makes sure the color is shown as a subcolor of another color, grouped together)
- `examplesSchema`
(this is an array with the EasyForms schema to show some examples on the right)
(can be inline or can be a path pointing towards a json or js file that should export the schema array as default export)

Ways of tackling this:
- https://github.com/TheRealSyler/sass-lsp-server/issues/3
- or use `raw-loader` and write manual REGEX to get the job done lol

Start by locating the existing colors page and how SASS assets are currently loaded. Compare the sass-lsp-server approach with raw-loader and manual parsing; done means a SASS color definition can expose name, value, description, grouping, and examples as JSON and render the requested classes, variables, and examples.
