Excellent Helper! I'll add some clarification about how to implement this for other devs.

In settings.yml you have to configure standard_helpers, not default_modules, like ie:
standard_helpers: [Partial, Cache, glxAsset]
You want to include Partial and Cache, which are the default ones

If you like to do this in a "by template" fashion, you can add this line at the beginning of your layout.php:
<?php use_helper('glxAsset') ?>

How this tips helps others..
