Inline worker script in legacy build

Older browsers that arleady supported es6 did not support dynamic imports.
Also change worker output type to esm as the build is slightly smaller.

+This library uses ECMAScript 2017 features like `async` functions. If you need to support old browsers, you can use `qr-scanner.legacy.min.js`, which is ECMAScript 2015 (ES6) compatible. Note, that the legacy build is larger as it includes some polyfills and inlines the worker script to support browsers that don't support dynamic imports. The worker script however, will need to be loaded in legacy browsers anyway.
