Add more benchmarks in ArkScript

We currently only have Ackermann Péter function, Fibonacci, some quicksort... but we could always use a little more benchmarks!

Don't hesitate to submit benchmarks in
- Java
- Javascript
- Python
- Ruby
- Perl
- C++
- Lua
- ArkScript
- any other mainstream language

No need to provide a benchmark **for every language**, even if you provide a single Java benchmark, it's fine, we can translate it in the other languages later!

Inspect the repository's existing Ackermann, Fibonacci, and quicksort benchmarks to understand its layout and conventions. Choose one listed language, add a comparable benchmark, and verify that it runs consistently with the existing benchmark collection.
