Original image does not render

Problem/Motivation

On a public asset, there is an option to use the original image in the UCV DAT select list. See the attached screenshot. However, the image does not render with the Bynder field formatter and a warning is displayed.

Warning: Undefined array key "original" in Drupal\bynder\Plugin\Field\FieldFormatter\BynderFormatter->viewElements() (line 302 of modules/contrib/bynder/src/Plugin/Field/FieldFormatter/BynderFormatter.php).

Rendered code:

<img class="bynder-image" loading="eager" alt="">

Steps to reproduce

Mark an asset as public in Bynder. Set up an entity browser with Bynder single selection for DAT and try rendering the original image.

Proposed resolution

Dynamically add original URL to thumbnails in BynderFormatter since it is only applicable to public assets.

Remaining tasks

Review MR and iterate.

Add test coverage.
