PDFBOX-6268: replace keycache to avoid rebuilding it again and again as
proposed by Tim Allison
> Avoid rebuilding key cache when possible
> ----------------------------------------
>
> Key: PDFBOX-6268
> URL: https://issues.apache.org/jira/browse/PDFBOX-6268
> Project: PDFBox
> Issue Type: Task
> Components: Parsing
> Reporter: Tim Allison
> Assignee: Andreas Lehmkühler
> Priority: Minor
> Attachments: G7BO7PNCCREVF2BCY5YSYOPYDLMBYASY.pdf,

> Over on Tika, we found that our {{COSDocument.getObjectsByType(FILESPEC)}}
> was really expensive on a couple of PDFs.
> The issue was that every object stream parse rebuilds the cache from scratch:
> xref entries × object streams map insertions.
> With incoming PR, we could get >600s -> ~4 seconds or less.
