Jonas Jenwald ae4f1ae3e7 Ensure that ChunkedStream won't attempt to request data *beyond* the document size (issue 14303) ...

This bug was surprisingly difficult to track down, since it didn't just depend on range-requests being used but also on how quickly the document was loaded. To even be able to reproduce this locally, I had to use a very small `rangeChunkSize`-value (note the unit-test).

The cause of this bug is a bogus entry in the XRef-table, causing us to attempt to request data from *beyond* the actual document size and thus getting into an infinite loop.

Fixes *one* of the issues listed in issue 14303, namely the `PDFBOX-4352-0.pdf` document.
