Converts CSV, xlsx/xls/ods, directories, ZIPs and globs into one INSERT
file per table. Producer-specific layouts (header/data rows found by a
marker cell) and sheet naming live in a gitignored dataconvert.json, with
dataconvert-example.json as the template. --max-rows samples each table
and SCHEMA.md records columns, types, row counts and full sizes.
