Support for Eloquent hidden attributes in discoverProperties

[andrew-alchemy]

When discovering Eloquent models it would be really useful to allow for some of the underlying table columns to be suppressed by respecting the "hidden" property of the Model. I very rarely want to expose every column of my tables.
In the SQLSchema trait I think we just need something along the lines of this (after checking we are in an EloquentEntitySet and $this->model is set)
$blacklist = array_merge( $blacklist, $this->getModel()->getHidden());

That's an excellent shout @andrew-alchemy, really Lodata should follow more of the rules in https://laravel.com/docs/9.x/eloquent-serialization#hiding-attributes-from-json. I will look into this.
