Issue 416

Some features that needed to be implemented to prove that the issue in #416 (closed) is unrelated to the scan_base or the multi-chip feature and that correlations in observations have been misinterpreted as causality.

• Enhance bdaq mock
• Fix CLI
• Add dry run feature to CLI
• Add CLI test: check that independent if the scan is called via CLI or in a meta scan, bdaq creates the same command stream. Validated with itkpixv1 / rd53a double chip module
• Do not require ptot info in testbench yaml for itkpixv1
• Deactivate slow data base contacting in unit tests to increase scan speed
• Use different chip_id for chips in a module
