Feat: Native hierarchies for elements from pptx documents (#1616) ...

## Summary
**Improve title detection in pptx documents** The default title
textboxes on a pptx slide are now categorized as titles.
**Improve hierarchy detection in pptx documents** List items, and other
slide text are properly nested under the slide title. This will enable
better chunking of pptx documents.

Hierarchy detection is improved by determining category depth via the
following:
- Check if the paragraph item has a level parameter via the python pptx
paragraph. If so, use the paragraph level as the category_depth level.
- If the shape being checked is a title shape and the item is not a
bullet or email, the element will be set as a Title with a depth
corresponding to the enumerated paragraph increment (e.g. 1st line of
title shape is depth 0, second is depth 1 etc.).
- If the shape is not a title shape but the paragraph is a title, the
increment will match the level + 1, so that all paragraph titles are at
least 1 to set them below the slide title element
