Sass support

[TheJaredWilcurt]

We could add in functionality to detect if a style input is .scss or .sass. Or have a type option for data.

redPerfume.atomize({
  tasks: [
    {
      styles: {
        in: [
          './styles/file.scss',
          './styles/style.css',
          './styles/stuff.sass'
        ],
        out: './dist/styles/styles.css'
      }
    },
    {
      styles: {
        data: '$cow: #F00; .moo { color: $cow; }',
        type: 'scss',
        out: './dist/styles/custom.css'
      }
    }

  ]
});

Implementation:

1. Detect the input type by str.endsWith('.sass') or str.endsWith('.scss').
2. Run the file through a Sass processor to create CSS (likely sass.js or a dart-sass binary since node-sass is no more)
3. Atomize the CSS like normal
4. If we allow strings of Sass to be passed in via data, then there needs to be a type or language or syntax or something that defaults to css, but allows sass and scss to be passed in as options.

Questions:

1. Should we allow users to pass in sass.js/dart-sass specific options?
2. What would that look like in the API?
3. Some options will need to be handled by Red-Perfume anyway, like using indentedSyntax setting for .sass
