Unused partials

Unused partials (that are only imported but not rendered) shouldn't alter the TOC

import UnusedPartialImport from './_partial3.md';

NonExisting Partials

Partials that do not exist should alter the TOC

It's not the responsibility of the Remark plugin to check for their existence

import DoesNotExist from './_doesNotExist.md';

Duplicate partials

It's fine if we use partials at the end

And we can use the partial multiple times!
