Fix  Codacy Static Code Analysis Issues

- The method exportOrDownload() has an NPath complexity of 300. The configured NPath comp1lexity threshold is 200.
- The method exportOrDownload() has a Cyclomatic Complexity of 13. The configured cyclomatic complexity threshold is 10.
- Avoid using static access to class '\OpenSpout\Common\Entity\Row' in method 'writeHeader'.

Fix  test with 'ubuntu-latest, 8.1, lowest' build

Extract Cell and Row creations to single methods

Remove static Cell creation from Exportable trait
