Subject: [PATCH] Add prog arguments to ArgumentParser to prevent the wrong
 inferred name

when calling like 'python -m cibuildwheel', we get errors like

usage: __main__.py [-h] [--platform {auto,linux,macos,windows}] [--archs ARCHS] [--output-dir OUTPUT_DIR] [--config-file CONFIG_FILE]
                   [--print-build-identifiers] [--allow-empty] [--prerelease-pythons]
                   [package_dir]
__main__.py: error: unrecognized arguments: --sad

With this change, we get error outputs like:

usage: cibuildwheel [-h] [--platform {auto,linux,macos,windows}] [--archs ARCHS] [--output-dir OUTPUT_DIR] [--config-file CONFIG_FILE]
                    [--print-build-identifiers] [--allow-empty] [--prerelease-pythons]
                    [package_dir]
cibuildwheel: error: unrecognized arguments: --asda
