[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

Expected behavior
A clear and concise description of what you expected to happen.

Desktop (please complete the following information):

• OS: [e.g. iOS]

Additional context
Add any other context about the problem here.

Start by running the two provided ./stackql Snowflake commands and comparing their timings, using the referenced screen capture as context. Trace the output handling path for the fat-row and tall-column cases, then add or run benchmarks covering both queries; done means their processing time is demonstrably improved.
