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, ensure Node.js is installed.
Navigate to www.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 with time 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.)

	0x00 - NUL - Null character, used as a string terminator in some programming languages
	0x01 - SOH - Start of Header, indicates the start of a message in communication protocols
	0x02 - STX - Start of Text, marks the end of the transmission header and the beginning of the message
	0x03 - ETX - End of Text, signifies the end of a message
	0x04 - EOT - End of Transmission, marks the end of a message or series of messages
	0x05 - ENQ - Enquiry, requests an acknowledgement from the receiver in communication protocols
	0x06 - ACK - Acknowledge, confirms receipt of a message in communication protocols
	0x07 - BEL - Bell, triggers an audible bell or alert on a device
	0x08 - BS - Backspace, moves the cursor back one space in text processing
	0x09 - HT - Horizontal Tab, moves the cursor to the next tab stop in text processing
