Would it be possible to add export of changed files to stdout/output file?

Right now dive has --json switch but it only exports statistics. It would be very beneficial to be able to export each layer file changes to an output file or stdout for automated postprocessing.

For example in my case I need to setup automated validation of Docker images based on if they have some files added with specific extensions or not. If dive would provide ability to export the layers files to stdout or output file then I could postprocess it with either jq or plain grep..

Maybe just an additional verbosity switch after --json could be added?

dive localhos/random-image:latest --json parsed_data.json --verbose

And that parsed_data.json would include also lists of all the files modified in each layer?

Personally I'd have it as the default, though if compatibility with the original fork is desired it could make sense.

Having verbosity levels could be a thing, in stuff like pytest you can do -v -vv etc. (Here there is only one level being proposed for now).
