Tweak

• Optimized recognition of invalid length values in stream objects.
• Added SetaPDF_Core_Writer_CopyStreamInterface interface.
• Implemented copyStream() method of SetaPDF_Core_Writer_CopyStreamInterface in SetaPDF_Core_Writer_Stream and SetaPDF_Core_Writer_TempFile.
• Make use of SetaPDF_Core_Writer_CopyStreamInterface in SetaPDF_Core_Reader_Stream::copyTo() and optimized method to reduce memory usage.
• Ensure string type for passwords in standard security handler classes (fixes a deprecation warning in special situations on PHP >= 8.1).
• Use predictor function when compressing cross-reference streams.
• Added getIndirectReference() and marked getReferenceTo() as deprecated in SetaPDF_Core_Document_OutlinesItem.
• Harden data types by using SetaPDF_Core_Type_*::ensureType() calls and explicit data type checks.
• Check for string parameter in constructor of File reader classes.
• Renamed factory() method of all security handler generator classes to create() (old method is marked as deprectated).
• New created security handlers are attached to their document instance automatically now (no need to call $document->setSecHandler($secHandler) afterwards anymore).
