Add mlr describe schema/shape introspection verb (#2098 PR6) (#2132)
One output record per input field: types seen with counts, occurrence
count, null count, cardinality, min/max, and -- for fields within the
-n/--max-values cap -- the complete distinct-value list in first-seen
order. `mlr --ojson describe` is the machine-readable form; nested
types/values flatten in tabular formats.
