🧩✨ make new Jekyll layout that compresses HTML as Plugin

[DerekNonGeneric]

@DerekNonGeneric, consider whether we'd be able to get this rude boy (🤬ish) out-of-sight, out-of-mind (i.e., gem plugin delivery via repo url - no need to publish to RubyGems for all of eternity)

E.g.:

gem "jekyll-assets", git: "https://github.com/envygeeks/jekyll-assets", group: :jekyll_plugins
