When parsing mappings, the code at [translator_new_rml/src/extractors/source/mod.rs#L67-L71](https://github.com/RMLio/mappingloom-rs/blob/2cc6dbe08fe6708d89948deb8be974cd1e4ac01c/crates/translator_new_rml/src/extractors/source/mod.rs#L67-L71) eagerly unwraps the source type. When no source type is present, however, this results in an uncaught error.
