Remove loading jQuery and customize-preview

Hello,

This plugin loads jQuery and customize-preview on frontend which is likely not needed: At following code:

wp_enqueue_script(
	'cncb_banner',
	CNCB_URI . '/js/cookiebanner.js',
	array( 'jquery', 'customize-preview' ),
	CNCB_VERSION,
	'true'
);

Can be likely replaced with:

wp_enqueue_script(
	'cncb_banner',
	CNCB_URI . '/js/cookiebanner.js',
	array(),
	CNCB_VERSION,
	'true'
);
