Improve slang-test output verbosity control (#7625)

* Improve slang-test output verbosity control

This commit improves the existing command-line argument for slang-test,
"-v". Previously it printed more information when "-v" was used.

This commit adds a new option to silence the information output so that
LLM processes less tokens when things are working as expected.

* format code (#74)
