added exclude post_formats

Thank you very much for this great plugin.

Instead of excluding post_types, I wanted to exclude some post formats (especially, the “video” format, because I want the video to be seen in the feed, not the featured image).

So, in function easy_add_thumbnail, I added :

$post_format	  = get_post_format( $post->ID );
		$exclude_formats     = array( '' );
		$exclude_formats     = apply_filters( 'eat_exclude_formats', $exclude_formats );

and I replaced

if ( ! in_array( $post_type, $exclude_types, true )) {

by

if ( ! in_array( $post_type, $exclude_types, true ) && ! in_array( $post_format, $exclude_formats, true ) ) {

In my child_theme functions.php I included an adaptation of your FAQ code:

//Easy Add Thumbnail: exclude post formats from adding a featured image
add_filter ('eat_exclude_formats', 'my_excluded_formats', 10, 1);
function my_excluded_formats ( $exclude_formats ){
    $exclude_formats[] = 'video'; 
    return $exclude_formats;
}

As far as I have tested, it seems to work.
Maybe something that could be included in a future release.

thanks again for your great work.
