9744414c66 Enable finer grained control of stream decoding 
This commit adds several API methods that enable control over which
types of filters QPDF will attempt to decode. It also adds support for
/RunLengthDecode and /DCTDecode filters for both encoding and
decoding.

e0d1cd1f4b Fix test case 
There was an unintended recoverable error in a test file. It wasn't
hurting anything, but it was obscuring the actual intent of the test.

ae0399ef87 Revert "Add page rotation example in contrib" 
This reverts commit 8ee83ca722.

This is being removed because qpdf now has its own page rotation. The
example was an excellent contribution to qpdf, but now it illustrates
rotating pages "by hand", which is no longer needed because of
QPDFObjectHandle::rotatePage.

an exception. A coverage case is commented out here and added in a

8ee83ca722 Add page rotation example in contrib 
This is added to contrib rather than examples because it requires
c++-11 and lacks a test suite, but it is still useful enough to
