Add more camera testing scripts or tests

@martin.kepplinger you have a nice summary at linux!430 (closed) - can we get those into either the pytests or as interactive tests? We could either dump those into test_scripts or (preferred) make them interactive and check some basic properties of the raw file?

I can look at that but wanted to check if you have more recent versions or even better tooling?

Having easier debugging tools at a "well known" location would be nice.
