The stream filter is only used if the stream is filterable, therefore
there is no point continuing to set decode parameters once it is recognized
that the stream is not filterable.

Fix bugs found during fuzzing

Fail if a bad token is encountered while parsing an array or dictionary
with more than 100,000 elements.

Fixes oss-fuzz case 388571629.

Fixes oss-fuzz case 394129398.

Issue arose from chaining multiple runlength filters and inflating a
compressed stream of ~100 bytes to several gigabytes.

There is no obvious fix without imposing an arbitrary implementation limit
and therefore potentially excluding valid PDF files.

Add zopfli support

Refine xref reconstruction (fixes #1335)

When recovering XRef streams, start with the stream with the largest
/Size rather than the largest offset.

Also, if reconstruction fails to find a trailer with a valid /Root entry
search for a root object.

Change QPDFWriter stream_decode_level default to qpdf_dl_generalized (fixes #1286)

CLI reject flags with parameters (fixes #1329)

Add new object stream test case

Exercise stream containing objects with no white-space between them.

stream_decode_level, but disable preserve_encryption if compress_streams is
false.

Fixes #1286
