Ability to set assets enqueue priority via configuration file

[amostajo]

Currently, this is set to load at priority 10 (default on every WordPress hook).

Add the ability to set the hook priority via app/Config/app.php file, like:

return [
    'assets' => [
        'enqueue_priority' => 15,
    ],
];

Added priority, configurable as:

return [
    'autoenqueue' => [
        // Enables or disables auto-enqueue of assets
        'enabled'       => true,
        // Enqueue priority
        'priority'      => 15,
        // Assets to auto-enqueue
        'assets'        => [],
    ],
];
