Pods: 'Taggable' parameter not work fine

[mikados]

Setting the "Taggable" parameter within a Pods field has no effect. It always appears as "Taggable" without the option to disable it.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Edit a Pod'
2. Click on one of the 'select' fields
3. Within the field options, click on the "Additional field options" tab
   4 .Uncheck the 'Tagtable' checkbox option, unchecking this option should not allow adding new values to the "Select2 tag type"
4. Returning to the interface where this field is shown, we observe the error: Select2 continues to allow new values to be added.

Expected behavior
The desired behavior should be that if we activate the "Taggable" checkbox it would allow adding new elements and if we deactivate it, it would not allow adding new elements.

Additional context
The problem occurs because the value that is saved from the input is "0" a string, and the fieldConfig.pick_taggable attribute expects to receive a Boolean.

Possible Workaround
I have solved the problem by forcing the string to be converted to the corresponding Boolean. For example, I convert the string "0" to the Boolean true and the string "1" to the Boolean false in the file: pods/ui/js/pods-dfv/_src/pick/views/select-views.js (line 347):

if ( fieldConfig.pick_taggable === '1' ) {
    fieldConfig.pick_taggable = true;
} else {
    fieldConfig.pick_taggable = false;
}

But I think it is a bad solution since this problem should affect all the settings of type "checkbox" whose values should be Boolean.

I am not an expert in the Pods code and that is why I have not been able to send you a PR
I hope someone skilled can fix the problem or help me with it.

Thank you
