feat: add benchmark repetition

[gusanthiago]

Hello there, this is related to this issue #6.

This PR aims to introduce benchmark repetition as an optional parameter. By running benchmarks multiple times and averaging the results, we can minimize noise and improve the accuracy of the measurements.

Below, you’ll find a comparison of benchmarks with repetition versus those without:

 node --allow-natives-syntax examples/create-uint32array/node.js

Let me know if need add something, thanks :)

Hey! Thanks for the PR

I'd just rename the "repetitions" to "repeatSuite". We run the benchmark multiple times already (benchmark runs * samples) and adding an option with that name would be misleading.

Could you also update the docs?

[gusanthiago]

Sure @RafaelGSS , I believe makes sense, I gonna update the docs and rename it
