BOE: chunk 'XUDLJYS-XUDLNGD' is invalid

• See download job: https://git.nomics.world/dbnomics-fetchers/boe-fetcher/-/jobs/390623
• Problem with the download of the chunk 'XUDLJYS-XUDLNGD' (requesting XUDLJYS, XUDLNDD, XUDLNDS, XUDLNGD does not work)
• Downloaded separately everything works fine (requesting XUDLJYS only is okay)
• This error prevents section I. Interest and exchange rates etc. (see website) to be downloaded
• Should we improve the code so that it stops crashing when a chunk is not correct?
