Port request: Header and Footer Scripts

[yorkshire-pudding]

Name of the module, theme, or layout
Header and Footer Scripts

Note there are also a couple of other D7 modules that appear to do the same thing (see https://www.drupal.org/project/add_js_css and https://www.drupal.org/project/admin_add_js) so one of those might satisfy the request.

This request is on behalf of forum member @suriyan2538 on https://forum.backdropcms.org/forum/how-do-i-insert-code-google-adsense-backdrop-cms-header

Link to the drupal.org module, theme, or layout
https://www.drupal.org/project/header_and_footer_scripts

(Optional) Link to an issue in the drupal.org queue asking the Drupal community if anyone is working on a Backdrop port of this project
TBC

(Optional) Bounty
