Disable Progress Bars on Non-Interactive Terminals

[traines-source]

in order to enable streaming and storing logs in CIs etc., detect whether stdout is redirected to a file or similar and in that case don't print deletion characters, progress bars etc, but just whatever has changed (percentage, label, etc)

maybe better: don't detect it, but create a command line flag for the import command. sometimes when redirecting to a file it's still nice to be able to tail -f and have the progress bars.

I assume that isatty() would be good to detect this.

I think both would be best: A user-friendly default, with the option to overwrite it for more specific use cases. This is how many well-known CLI tools do it.
