The main benefit of this is allowing the sort order to be controlled by
fields that don't necessarily need to be printed:
./scripts/csv.py input.csv -ba -sb -fc
By default this sorts lexicographically, but this can be changed by
providing an expression:
./scripts/csv.py input.csv -ba -sb='int(b)' -fc
Note that sort fields do _not_ change inferred by fields, this allows
sort flags to be added to existing queries without changing the results
too much:
./scripts/csv.py input.csv -fc
./scripts/csv.py input.csv -sb -fc
