Adding header info in the OfflineReader

As in the title, it would be nice to also have the header of the file accessible with OfflineReader.

changed title from Adding {-header info in the OfflineReader-} to Adding header info in the OfflineReader

changed the description

Yep, the offline header is still missing, I think @zaly has it already on the todo list but thanks for reminding us!

assigned to @zaly

added enhancement label
