0.8.5

Changed:

• Missing files no longer fail the complete search request, instead the OCR
  highlighting for the document is skipped
• Add support for Solr 9.5
• Updated documentation with warning for Solr 9 users to disable security sandboxing
  when using pointers to external files

Fixed:

• Regular highlighting in case no hl field can be determined works again (#404)
• Passage building across more than two concatenated files works now (#422)
