This allows for image filtering via Python expressions by the same metadata that is also used to build filenames (--list-keywords). The usually shunned eval() function is used to evaluate filter-expressions, but it seemed quite appropriate in this case and shouldn't introduce any new security issues, as any attacker that could do > gallery-dl --filter "delete-everything()" ... could as well do > python -c "delete-everything()"
