Add flag to install tosu

[NoelleTGS]

tosu is a more recent and user-friendly memory reader than gosumemory, so it would be nice to have a way to install it.

It's compatible with everything from gosumemory so replacing gosumemory support entirely might even be an option, though I don't know how needed that is.

I'll test and add it then, sure thing. Though I might need some time as I'd like for it to download the latest release without me needing to update it everytime (since I've seen it gets a lot of updates 🥇 )

Also I love how they already support the script 😭

I made PR for that
