output: decorate --human tables, color by tx type, IT datesv0.2.2

The --human transaction table now uses Italian dates (DD/MM/YYYY), a
header rule line, and colors each row by transaction type (withdrawal
red, deposit green, transfer cyan) when writing to a TTY. Colors are
suppressed when piped; JSON output is unchanged. Bump to 0.2.2.
