Fix bug in QPDFWriter::preserveObjectStreams
...
Code failed to allow for QPDF::getCompressibleObjSet deleting objects
from the object cache in case of multiple entries for the same object id.
Add fuzz test case 68668.

string_view leads to char_traits which is not standard C++ (background in #1024 ).
...
This triggers compilation failures with certain C++20 compiler configurations.
To avoid this I moved the cast to the loop's body.

Handle parse error stream data ( fixes #1123 )
...
A parse error in stream data in which stream data contained a nested
object would cause a crash because qpdf was not correctly updating its
internal state. Rework the QPDF json reactor to not be sensitive to
parse errors in this way.
