Snippets: Add/Remove “Blocks” (Sections) From Custom Post Type Entries

/**
 * Any custom post type post entry can be altered via the wpex_{post_type}_entry_blocks filter
 * which returns an array of the "blocks" or parts for the layout
 * that will be loaded from partials/cpt/cpt-entry-{block}.php
 *
 * Default array: array( 'media', 'title', 'meta', 'content', 'readmore' );
 *
 * You can use the filter to add, remove or re-order elements in the array as you wish.
 * Below is an example showing how to add a new block for a custom post type and remove one.
 *
 * After adding new blocks simply create a new file with the name "cpt-entry-YOUR_KEY.php"
 * and place this file at partials/cpt/ in your child theme.
 *
 * IMPORTANT: Make sure to change {post_type} with your post type name
 * IMPORTANT: Make sure to replace "YOUR_KEY" with the key given in the array (advertisement is the key for the block added below)
 *
