Customize Control: Radio Image
<?php
/**
* The radio image customize control extends the WP_Customize_Control class. This class allows
* developers to create a list of image radio inputs.
*
* Note, the `$choices` array is slightly different than normal and should be in the form of
* `array(
* $value => array( 'url' => $image_url, 'label' => $text_label ),
* $value => array( 'url' => $image_url, 'label' => $text_label ),
* )`
