Fix and short link support

Dear plugin author,

I added support for short links to the function and fixed some issues. Feel free to include my changes in the next version.

function the_post_qrcode( $size = '150', $opts = [] ) {
	$opts += [
			"fore_color" => null,
			"back_color"=> null,
			"margin" => null,
			"short" => false,
		];
	
	$src = add_query_arg( 'text', urlencode( $opts["short"] ? wp_get_shortlink() : get_permalink() ), site_url('/lh_qr_codes/') );
	
	if ($opts["fore_color"]){
		$src = add_query_arg( 'fore_color', $opts["fore_color"], $src );
	}
	
	if ($opts["back_color"]){
		$src = add_query_arg( 'back_color', $opts["back_color"], $src );
	}
	
	if ($opts["margin"]){
		$src = add_query_arg( 'margin', $opts["margin"], $src );
	}
	
	$src = apply_filters( 'lh_qr_codes_template_src', $src);
	
	echo '<img src="'.$src.'" height="'.$size.'" width="'.$size.'" />';
}

Best regards
