feat: support cite-group and cite-detail

Adds support for new cite-group syntax.
- transformer.js
  - copyable elements: add cite-group and cite-detail
  - passThrough elements: remove cite-group
- x.js
  - adjust check for articles since x is no w inside cite-detail (inside xref)
- test
  - article.xml: add test case
  - book.xml: add test case
  - add cite-detail test
  - element-cite-group: test article and book output
    Note: git is confused, thinking cite-group was renamed to
    cite-detail.

Resolves #443
