"2-up" command discards the last page of documents with an odd number of pages

Hi,

Execute this command: pdfly.exe 2-up test.pdf out.pdf. (test.pdf has an odd (3) number of pages).

Notice that the last page of test.pdf is absent from out.pdf, while it should probably be there.

Thank you for reporting this.

I confirm that this is currently a bug.
I have created this unit test for tests/test_up2.py reproducing the problem:

def test_up2_odd_page_number(capsys: pytest.CaptureFixture, tmp_path: Path) -> None:
    pdf_file = "sample-files/009-pdflatex-geotopo/GeoTopo.pdf"
    out_file_path = tmp_path / "out.pdf"

    # Ensure original page number is odd:
    in_reader = PdfReader(pdf_file)
    assert len(in_reader.pages) % 2 == 1

    # Act
    exit_code = run_cli(
        [
            "2-up",
            pdf_file,
            str(out_file_path),
        ]
    )
    captured = capsys.readouterr()

    # Assert
    assert exit_code == 0, captured
    assert not captured.err

    out_reader = PdfReader(out_file_path)
    assert len(out_reader.pages) == (len(in_reader.pages) + 1) / 2
