… simplify logic. Update related test outputs and release notes.

Introduce new methods: `data()` to access buffer content, `empty()` to check buffer state, and `size()` to retrieve buffer size. Update unit tests to validate the behavior of these methods alongside existing functionality.

qpdf permits replacing standard stream filters with user provided filters.
#1457 incorrectly removed that option.

Introduced explicit checks for empty streams and refined filtering conditions for improved clarity and correctness.

Fix QPDFFormFieldObjectHelper::getChoices (fixes #1433)

Add additional sanity check during xref recovery

Return the display value if the choices entry is an array of strings rather
than a single string.

Test file is need-appearances.pdf modified to contain one array entry.

Do not copy duplicate pages during xref recovery.

Thanks to github user @cdosborn for the basic enhancement.
