[Feature] Footer - add a part with an optional footer logo

Just as I had to change this, this might be a usefull idea for inclusion.

At the footer sometimes it's required to include "supporting org's logo's".
Just add such a 'section' for the logo before the copyright.

Below my partial, Needs eventually constant for the setup.

```

{settings.copyright.text}

```

Locate the footer template containing the footer-section-meta markup and inspect the existing settings.footer_logo, Navigation/Meta, and Navigation/Language entry points. Confirm how the footer configuration is defined, then make the logo section optional and place it before the copyright; done means the configured logo renders only when enabled and the existing footer remains unchanged otherwise.
