A simple Terminal-Based Game Launcher. Can be tweaked, i don't really care.
(LINUX ONLY, READ BELOW FOR OTHER OPERATING SYSTEMS)
On the last line of the `joingame()` function, I used "xdg-open" to open the roblox-player: link. This can be substituted for whatever macOS, Windows, or any other operating system uses.
I believe for windows it is `start` and for macOS it is `open`
