TOC tabs leader implementation missing

[anti-the-social]

Guten tag :)

One of the settings for the Table Of Contents is the leader character. (chars between the words and page number) It is implemented in Word via tabs.
new TableOfContents element has many settings just like it should, but we can't set paragraphs properties anyhow yet (I guess because TOC is two paragraphs.) It seems that first paragraph properties affect the whole TOC settings

One lifehack I tried is to set tabs and leader character to the attached style for the certain levels, but that didn't catch up, Word ignores it.

And if I manually add tabs for the first paragraph of the TOC element then Word catches what it meant to do

Solution:
I guess we should add additional property to ITableOfContentsOptions Interface, I would guess all the IParagraphOptions because at the moment I am not sure which other features TOC might require. (other than tabs)

Took this demo for testing: https://github.com/dolanmiu/docx/blob/master/demo/28-table-of-contents.ts
