Please add src to npm package

Hi, thanks for widget, looks very cool. But just want to import your component as ES module and let my bundler do all the job, shake the tree, generate src mapping and etc, because now it's a hell trying to debug minified dist version of your component. So, please, include src folder into npm package back.

["module-resolver", {
          "root": ["."],
          "alias": {
          "@": "./src",
          "%": "./tests"
          }
      }]

..oh noes, not a native esm syntax. Well, nevermind, sorry for taking the time. (I recommend to consider to have fully compatible ESM version of a package in the future)
