Add option to suppress progress

[thekid]

Inside GitHub actions or Azure pipelines, the progress spinner output is not helpful

Decide on what to do:

• Add --no-progress
• Detect we're not running in a TTY (is that so?) and do not display progress?
• Add --output=console (default) vs. --output=ci (which doesn't use progress indicators, but could also have other improvements)
• Use -r dots, see Extract output into a dedicated class #20
