Feature Request: CKEditor plugin user group permission to enable source editing

[svale]

Description

I would be super nice if we could combine enableSourceEditingForNonAdmins with a specific user group permission. For larger clients, we often have a Super User group that should have wider permissions than other editor groups, and specifically the privilege to see/edit a CKEditor field source.

I imaging this as plugin user group permission option:

In combination with an extended test before removing the button

if (!$this->enableSourceEditingForNonAdmins && !($Craft::$app->getUser()->checkPermission("ckEditor:viewSourceEditingButton") || Craft::$app->getUser()->getIsAdmin())) {
    ArrayHelper::removeValue($toolbar, 'sourceEditing');
}

(Hope you'll forgive me for adding a feature request as bug/issue since its the only option )

Thanks!
