[BUG] Displaying fat rows / tall columns is objectively too slow

Describe the bug

The output handling system does not process fat rows and tall columns in a timely fashion. Probably need to add benchmarks for this stuff into testing workflows. Please see screen capture.

To Reproduce

time ./stackql --auth="${AUTH_STR_SNOWFLAKE}" --registry="${REG_TEST}" "${TLS_CFG}"  exec "select id from google.compute.instances where project = 'stackql-demo' and zone = 'australia-southeast1-a' limit 1;" > /dev/null


time ./stackql --auth="${AUTH_STR_SNOWFLAKE}" --registry="${REG_TEST}" "${TLS_CFG}"  exec "select * from google.compute.instances where project = 'stackql-demo' and zone = 'australia-southeast1-a' limit 1;" > /dev/null

Additional context
Add any other context about the problem here.

Inizia eseguendo i due comandi ./stackql Snowflake forniti e confrontandone i tempi, usando la schermata acquisita di riferimento come contesto. Traccia il percorso di gestione dell’output per i casi fat-row e tall-column, quindi aggiungi o esegui benchmark che coprano entrambe le query; il lavoro è completato quando il loro tempo di elaborazione risulta dimostrabilmente migliorato.
