Option/subcommand to dump expected column and their order

[afranke]

It would be nice if the validator was able to just parse the schema, dump a list of expected headers in the correct order and exit. That could then be consumed by other tools that handle the CSV files to make sure their output will comply with that before submitting them for validation.

Thanks for the suggestion. I'm not sure when we'll next be working on the validator, but I'll ensure this is included in prioritisation (and we do of course welcome pull requests, this might be a relatively straightforward intro request).

If only it was Rust or Python… 😀
