Extract CLI to separate opencage-cli package

Remove command_line.py, batch.py, their tests/fixtures, and the
example batch.py + addresses.csv. The CLI now lives in its own
repository and PyPI package (opencage-cli).

Drop tqdm and certifi (only used by the batch CLI) and the
[project.scripts] entry point. Bump to 3.4.0.
