Explanation

From #3365 (comment):

Remaining max-complexity greater than 30

• pypdf/_writer.py, remove_objects_from_page: 31
• pypdf/_writer.py, merge: 31
• pypdf/generic/_data_structures.py, read_from_stream: 34
• tests/test_page.py, test_extract_text_visitor_callbacks: 37

We should try to refactor these methods where possible to reduce the complexity. The complexity mostly is due to functions nested inside methods. Getting rid of the nesting should fix the complexity.

• PdfWriter.remove_objects_from_page
• PdfWriter.merge
• DictionaryObject.read_from_stream
• test_extract_text_visitor_callback
• Reduce tool.ruff.lint.mccabe value.
