--no-headers doesn't work on most formats

Thanks, looks like a bug.

On consulting https://pypi.org/project/tabulate/ it looks like most of those formats don't actually makes sense without headers - so the right thing here might be to raise an error if --fmt and --no-headers are used at the same time.
