Add parameter for get_acf_post and get_acf_posts to bypass ACF formatting logic.

[Liblastic]

Sometimes you might want to use ACF fields but you don't want ACF to format data before you handle it. Now this is not possible because format_value has been hard coded for ACF function get_field_object on these lines (See the links below.). https://github.com/devgeniem/dustpress/blob/master/classes/query.php#L114 https://github.com/devgeniem/dustpress/blob/master/classes/query.php#L288

After changes ACF format_value cloud be true by default but you can change it to false in function $args if you want to.
