How to play ASCII-Art Star Wars offline

Following will teach you how to play the "easter-egg" (which actually isn't, but many people describe this as an easter egg) of ASCII-Art Star Wars (or Star Wars in terminal/telnet, whatever), the one you normally starts like this:

$ telnet towel.blinkenlights.nl

Before you start, ensureNode.js is installed.
Navigate towww.asciimation.co.nz, the original home of that ASCII-Art Star Wars.
Press F12 to open developer tools.

I implemented simple (dumb) algorithm for finding the largest Collatz trajectory(see Collatz conjecture)for all numbers < 100,000,000 in Python, Rust and Elixir.

I benchmarked them withtime command, assuming boot time is negligible(Python and Elixir need ~1 sec to boot before the calculation loop starts but their runtime is in hundreds of seconds anyway.Rust program boots in couple of milliseconds.)
