kax_analyzer_c: allow caller to take care of mandatory elements

Browse Source 
Chapters and tags in WebM only allow a subset of elements, among them
certain elements that are mandatory in Matroska. So if the caller is
already aware of that, it can take care of them properly so that the
analyzer doesn't have to anymore.
