Selectbox: Numeric choice values are not working

[shofer]

Thanks for providing this library :)

There seams to be a type mismatch if you define numeric values for your choice values.
PHP transfers them into int but in the values from get_option are always strings.

Example Configuration:

        'sample-page' => array(
            'page_title' => __('Sample Page', 'sample-domain'),
            'sections' => array(
                'sample-section' => array(
                    'title' => __('Section One', 'sample-domain'),
                    'fields' => array(
                        'select' => array(
                            'title' => __('Select', 'sample-domain'),
                            'type' => 'select',
                            'value' => 'option-two',
                            'choices' => array(
                                '0' => __('Nothing selected', 'sample-domain'),
                                '1' => __('Not working', 'sample-domain'),
                                'x' => __('Working', 'sample-domain'),
                            ),
                        ),
                    )
                )
            ),
        ),
    );

Try to select the "Not working" choice.

PHP Array:

    var_dump(array(
        '0' => __('Nothing selected', 'sample-domain'),
        '1' => __('Not working', 'sample-domain'),
        'x' => __('Working', 'sample-domain'),
    ));

array(3) {
--
  | [0]=>
  | string(16) "Nothing selected"
  | [1]=>
  | string(11) "Not working"
  | ["x"]=>
  | string(7) "Working"
  | }

get_option

var_dump(get_option('sample-page', array() ));

array(1) {
--
  | ["select"]=>
  | string(1) "1"
  | }

My use case is to save have a dropdown for all categories, I would like to save just the id of the selected category, but at the moment I have to add a string prefix to make it work

+1. Right now I'm having to concat a string onto the ID, and then remove it later.
