JS - Handle correctly hierarchy of fields (#13133)
* JS - Handle correctly hierarchy of fields - it aims to fix #13132; - annotations can inherit their actions from the parent field; - there are some fields which act as a container for other fields: - they can be access through js so need to add them with an empty type (nothing in the spec about that but checked in Acrobat); - calculation order list (CO) can reference them so need make them through this.getField; - getArray method must return kids. - field values are number, string, ... depending of their type but nothing in the spec on how to know what's the type: - according to the comment for Canonical Format: https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf#page=461 - it seems that this "type" can be guessed from js action Format (when setting a type in Acrobat DC, the only affected thing is this action). - util.scand with an empty string returns the current date.
