stop_loading_unused_blocks _crap.php

//In a better world block's author makes sure the block's assests are loaded only if block is actually in use (via enqueue_block_assets). For other cases:

function sz_stop_loading_unused_block_crap( $tag, $handle, $src ) {
	// Check if block's assets are loaded 
	if (str_contains($src, 'plugins/wp-swiper')) {	//plugin directory here 					
		 if (is_singular()) {// works only on Singular
			 //TODO: //Will work for content only. if block is elsewhere or post it's archive use this https://wordpress.stackexchange.com/questions/392493/find-if-widget-block-is-active
     	 $id = get_the_ID();	
			if (has_block('da/wp-swiper-slide', $id) !== true) { //block name here
				// to find out the name of the block in Browser Inpector (not source code) ctrl+f for "data-type"
				$tag = '';
