Support formatting of section headers above h6, correct computation of level

[sglaser]

Headers above h6 will be of form <h6 class="h7"> so css can do magic.

The level computation assumed section numbers and appendix numbers were a single digit/character

I'll add a test for this. Please review but don't merge yet.

I'm a bit concerned about the accessibility implications of this. As per following page from WAI wiki, the recommended way of supporting heading level beyond h6 is:

<div role="heading" aria-level="7">Jonagold/div>

Also see: https://stackoverflow.com/questions/55891025/is-h6-aria-level-7-a-reliable-way-to-create-a-h7-element

If it's fine to treat all headings above h6 as h6, I think this would be fine though.

I understand the implications of deep nesting. I’m faced with an existing specification that I can’t change that uses h7. I’ll fix the “bug” where I unnecessarily checked for an empty classList. Steve Glaser sglaser@sglaser.com

@stevefaulkner or @patrickhlauke, we could use your guidance here: if we want a "h7", should we do <h6 aria-level="7"> or just use a <div role="heading" aria-level="7"></div>?
