    Fix use-of-uninitialized-value in XRef
    
    Attribute `keyLength` of `XRef` is not initialized on object creation, and is subsequently used, for instance in `XRef::fetch` ([poppler/XRef.cc:1214](https://gitlab.freedesktop.org/poppler/poppler/-/blob/e0148dbc9a0189d1ee982a1b3e763930e086b919/poppler/XRef.cc#L1214)). This was flagged by running `MemorySanitizer`.
