Running eleventy-plugin-styles fails due to peerDependencies after yarn install

Since yarn does not automatically install peerDependencies, the plugin fails while trying to load the peerDependencies. Perhaps you'd consider making all the peerDependencies straight dependencies since the plugin relies on them to run?

Inspect the package metadata for eleventy-plugin-styles and compare its peerDependencies with the dependencies needed when the plugin loads. Reproduce the failure after yarn install, then verify that the plugin runs successfully without separately installing those peer dependencies.
