Description

I'm not sure how this works, but there are measures in statistics to be confident of your results (standard deviation we have and I think it is one of them) - with this given we could add an option that says benchmark until this confidence level is reached, with some timeout though so it doesn't run forever if results vary too much naturally.

Research direction
Investigate how existing options like :time and :warmup are implemented in the benchee library (e.g., Benchee.Configuration and Benchee.Runner). Understand how to add a new option that triggers termination based on a confidence threshold. Consider using statistical formulas for confidence intervals and refer to linked issue #9 for discussion. Ensure a timeout mechanism to prevent infinite runs.
