csvclean: Provide machine-readable output

[hseg]

Trying to solve #962 automatically, but csvclean emits its output in an inconvenient format. Would it be possible to have it emit its output in a programmatically-readable format?
Eg have csvclean --machine-readable emit a table in the format

rule,affected_lines,fix_parameters

so that I could just csvcut $(csvclean --machine-readable | csvsql 'select fix_parameters...')
Alternatively, just give csvclean an --autoclean command that executes the cleaning routines it suggests.

Have you read the docs and are you using the most recent version? The output is already formatted as CSV. https://csvkit.readthedocs.io/en/latest/scripts/csvclean.html

Sorry, I was unclear. The problem with the current output is that the column numbers are embedded in the output string, making programmatically getting them more difficult and fragile. What I'm after is that there either be a way of getting the parameters for the fix out or of automatically attempting the fix, so that there is some direct composition of the provided commands that is guaranteed to produce a CSV file not triggering these warnings.

I would accept a PR that adds columns for those numbers.

Alternatively, I would accept a PR that adds a --remove-empty-columns option to csvclean.
