Same as include_template_part, require, include, but allows for arguments to be passed into template file.

hm_get_template_part.php

/**
 * Like get_template_part() put lets you pass args to the template file
 * Args are available in the tempalte as $template_args array
 * @param string filepart
 * @param mixed wp_args style argument list
 * @example hm_get_template_part( 'template_path', [ 'option' => 'value' ] ); ---> then in template: $template_args['option'];
