How to build a slider with table of content?
On version 3.1.1 I was using .number but after bumping to 3.9.0 I have a problem.
Somehow I need to get page number from created slide.
Is there any other good solution (API?) to create table of content?

Observed Behavior

Long time ago there was a function getPageNumber() (#353)
Version 3.1.1 returned a number const slide = pptx.addSlide('Page number'); return slide.number;.
On version 3.3.0 .number was changed/renamed.
Apparently on 3.9.0 there is an attribute slide._slideNum but using TS there is no clean approach to get it. TS documentation suggest .slideNumber but it's not supported by the code.

Steps to Reproduce

V 3.2.1 https://codesandbox.io/s/pptxgenjs-page-number-3-2-1-hqew7?file=/src/App.js
V 3.9.0 https://codesandbox.io/s/pptxgenjs-page-number-3-9-0-2n9js?file=/src/App.js

The ability to retrieve the slide number was removed as it did not seem useful. It also conflicted with the newer property for the Slide Number prop (SlideNumberProps) used to set slide number on the slide.

As the developer, you can track how many slides have been returned.

If anyone else needs to know the slide number after adding tables with autoPage: true, you can access it with slide._slideNum. The only downside is that you'll need to add another slide after the table to access it. See: #1149 (comment)
