* [FIX] All of the sudden asserting http:location/3 throws warnings. Turned into normal assertions everywhere.
* [FILE_EXT,FIX] file_name_type/3 would fail for files with an extension with no registered type. Now it succeeds with `Type` uninstantiated.
* [RDF_CONTAINER,FIX] Adding members to large containers is much more efficient now.
* [XML_TO_RDF,NEW] Added an XML parser that asserts RDF. Coming from project EnergyLabels.
