For more information about pkg: importers, see the
announcement on the Sass blog.

Command-Line Interface

• Add a --pkg-importer flag to enable built-in pkg: importers. Currently
  this only supports the Node.js package resolution algorithm, via
  --pkg-importer=node. For example, @use "pkg:bootstrap" will load
  node_modules/bootstrap/scss/bootstrap.scss.

JavaScript API

• Add a NodePackageImporter importer that can be passed to the importers
  option. This loads files using the pkg: URL scheme according to the Node.js
  package resolution algorithm. For example, @use "pkg:bootstrap" will load
  node_modules/bootstrap/scss/bootstrap.scss. The constructor takes a single
  optional argument, which indicates the base directory to use when locating
  node_modules directories. It defaults to
  path.dirname(require.main.filename).
