Thanks for your first pull request!

A few things:

• Typing: As long as we support Python 3.7 and 3.8, my understanding is that we need to use typing.Tuple. https://stackoverflow.com/a/39458225/1116842
• Why is it better to use ExitStack instead of nullcontext?
• Can you please investigate the failing test?
• I can see how relative paths in the examples fit more environments (e.g. non-Unix). I think it would be better to write to local *_out folders (inside the examples directory, e.g. flowcam_out). These need to be added to .gitignore as well.
