How to load Custom Product Builder Scripts Asynchronously?

Sometimes due to theme conflicts you need to load CPB scripts asynchronously. You need to change the regular script tags:

{{ 'https://code.jquery.com/jquery-3.0.0.min.js' | script_tag }}
{{ 'https://cdn.shopify.com/s/assets/external/app.js' | script_tag }}

to

<script src="https://code.jquery.com/jquery-3.0.0.min.js" async></script>
<script src="https://cdn.shopify.com/s/assets/external/app.js" async></script>
