Build LESS with an 11ty transform. The magic happens in .eleventy.js and src/pages/_less.liquid.
Also includes a very basic Gulp clean process.
Requires Node 10+ (for 11ty)
npm ci
npm run build
builds to _site
npm run dev
spins up http://localhost:8080 and watches for changes
npm run clean
removes 11ty build folder, automatically run before dev and build
