* Detect Isso API endpoint. There are typically two use cases:
*
* 1. use minified, single-file JavaScript. The browser interprets
* scripts sequentially, thus we can safely use the last script
* tag. Then, we chop off some characters -- /js/embed.min.s --
* and we're done.
*
* If the script is not served by Isso directly, a custom data
* attribute can be used to override the default detection
* mechanism:
*
* .. code-block:: html
*
* <script data-isso="http://example.tld/path/" src="/.../embed.min.js"></script>
