We love tests. This module has no tests. Solve this.
The module is simple, but we can test two things:
Test configuration form: check it renders and can be saved.
Test library is inserted when enabled on all pages: while this is not recommended in prod it allows to test Scrollama.js library can be loaded and it is working. This means that probably it will work on sites that add the library by other means.
Add test, check they work on Drupal CI.
