Custom aliases and casts for post meta not working

Description:

When defining the $aliases on a custom model, the meta fields aren't loaded correctly and the $casts seem to be ignored. ~~(On a side note, default post aliases don't seem to be inherited correctly, like title or slug etc. I need to define them all as well.)~~ Fixed by adding use Corcel\Concerns\Aliases; to custom model.

Setting the meta data keys in $appends works correctly, but the $aliases seem to be ignored.

Maybe I'm missing something here?

Steps To Reproduce:

1. Create a custom model and extend Corcel\Model\Post
2. Add a custom meta field called channel_failures and set it to a value of 10.
3. Define a custom meta field in $appends and make an alias in $aliases, add field to $casts.

   protected $casts = [
       'failures' => 'int', // doesn't work
       'channel_failures' => 'int', // doesn't work
   ];
   
   protected $appends = [
       'failures', // doesn't work
       'channel_failures', // works
   ];
   
   protected static $aliases = [
       'failures' => 'channel_failures', // doesn't work
   ];    
   

4. Try it and see that it doesn't work as expected:

   MyPostType::first()->failures; // null
   MyPostType::first()->channel_failures; // "10" <- not being cast to int

After diving into the code, I found that meta field aliases need to be defined as an array:

protected static $aliases = [
    'failures' => ['meta' => 'channel_failures'], // works!
];    

Still no luck with the $casts yet
