Add transform "unwrapBlockByKey" and "unwrapInlineByKey" (#390)

* Add transform .unwrapInlineByKey with test and documentation

* Add transform .unwrapBlockByKey with test and documentation

* add failing test for unwrap limited to a range

* Improve creation of selection in unwrap[Inline|Block]ByKey

* Adapt unwrapInlineAtRange to take range in consideration

* Add test to unwrapInline only one in the document
