• utilsScript option and loadUtils method now load the utils script using a dynamic import as opposed to injecting a new script tag.
• To make this work, the utils script (build/js/utils.js) is now an ES Module, which no longer uses any globals, like window.intlTelInputUtils (etc). This means it will no longer work to pre-load the utils script yourself, hence the new bundles (see next point).
• For those who are not worried about file size, we now provide two bundles which include the utils script: build/js/intlTelInputWithUtils.js and react/build/IntlTelInputWithUtils.js. If you're using ES Modules, you can import these as "intl-tel-input/intlTelInputWithUtils" and "intl-tel-input/reactWithUtils" respectively (TypeScript types included in the regular declaration files).
